It's your lucky day A mod post from me after not modding anything for 2 weeks 
For m4m and I liked the preview for this song. Modding this at 3am so I may make silly mistake and I haven't mod in a long time so sorry if I disrespect your mapping style/try to force my mapping style into your map. Remember that everything is just suggestion unless stated otherwise and if I give a long mod, I'm only trying to improve your map[
General]
- Hmm no higher quality video? Well I guess it's fine.
- Maybe name SinDemon's Insane to something else? Like SinDemon's Extra? Seem nicer then to see two Insanes. Or something related to the map, I notice this diff has small circles so maybe something related to it.
- What is Vocaloid2 :S. I checked this and some ranked map has this tag too. What is it?
* I've heard some Nico Nico Chorus song before and there is usually a list of who sang this? Like
http://www.youtube.com/watch?v=OhQ6GQW2lA8 8 people in the description is who sing this. I think this is important since Usa & Hanatan have a couple ranked map on osu (not sure about other singers) and would be a shame if they sang in this chorus and their names not include in the chorus so I recommend checking this.
- Toku-P is composer?
Source: This field should generally only be included for Anime or Video Game songs, and occasionally for Novelty (Movies, TV, or Internet) songs. If the song is from an anime or video game, or is most famous for its use as a TV or movie theme, the title of that source goes here. Rock and Pop songs should generally leave the field blank: This is not to be used for things like album titles, and video games like Rock Band or Guitar Hero, which use already-popular songs, should not be named here.
Nvm, he's a composer who made song and upload to Nico Nico Douga
http://vocaloid.wikia.com/wiki/Toku-P.
Put his name in tags and put Nico Nico Douga in source. I am aware of this map
http://osu.ppy.sh/s/16226, but should definitely be change to this. Also this
http://osu.ppy.sh/p/beatmaplist?s=7&o=1 ... 0&g=0&la=0- Use a silent slider slide for the beginning (not sure how many beatmaps you have, but I'm sure atleast one map you have contains silent slider track; search soft-sliderslide.wav and put it in your folder. Then in the timing setup panel, change the first timing point (the red one) to soft custom 1
http://puu.sh/i7Dg. Then put a timing point at 00:27:273 and change it back to default (to unsilent the slider track). Do this for all diff, slider track sound too loud here.
Should be all hopefully.

Easy]
- Considering there are 5 diff, I'm wondering why this diff doesn't use the lowest circle size.
Please use circle size 3, 4 is more fitting for Normal or harder.
- For a diff with this star rating, the difficulty setting are too high imo. I recommend Hp Drain 1-2, Approach Rate 2 and Overall difficulty 1.
- Hmm I recommend tick rate 1 since due to how slow the slider velocity is, make it all crunch up together and tick rate 2 doesn't work too well for the calm part.
00:00:00 - 00:25:792 - I see why you used ar3, lot of hit circles here. This is not nice to play for beginner due to how slow the approach rate is (you feel like hitting it too early) and you can easily do something else considering the music. I recommend slider (this is why I suggest tick rate 1 as the slider tick will sound overpowering at this part with tick rate 2 and silent slider slide). Basically this,
00:03:570 (1,2) - Slider start at (1) and ends at (2)
00:06:532 (1,2) - ^
00:09:495 (1,2) - ^ and put a new combo here (don't add any to previous notes or the next note)
00:12:458 (1.2) - ^
00:16:903 (4,1,2) - Repeating slider instead and add new combo here.
00:21:347 (1,2,3) - Same thing, no new combo.
Refer to this guide for interesting way to place these long sliders
viewtopic.php?f=56&t=37194. To be honest, just curving them and making them symmetrical works, example
http://puu.sh/i7Ge, but try to experiment a bit with other shape to make it more interesting.
00:27:273 (1) - Would be better if you try some slider shape rather than leaving it straight. Doesn't look nice for me to see long slider left as straight.
00:30:977 (1,2,3,1,2,3) - This really has to do with my mapping preference, but I don't like these hit circles. Same reason as before
This is not nice to play for beginner due to how slow the approach rate is (you feel like hitting it too early) and you can easily do something else considering the music. Consider this...
00:31:718 (2,3) - Slider (emphasize the finish) ---
A slider begin is more emphasize then it end.00:33:199 (1,2) - Slider instead for this as well.
00:39:125 (2,1) - A bit nazi, but move them more to the right, it looks like they touch the previous slider track so seem cleaner to move it.
00:39:495 (1) - This slider isn't perfectly symmetrical, be sure to refer to the slider guide I gave you to make it better.
00:41:532 (2,3) - Just my preference, but when note overlap each other like this in the easier diffs, I recommend a slider. Seem cleaner to me.
http://puu.sh/i7IU00:45:051 (5) - Make this symmetrical with (3)
http://puu.sh/i7Ki00:46:347 (1,2) - Same as 00:41:532
00:47:644 (1) - I recommend curving this slider, no real reason except that it looks nicer.
00:48:384 (2) - I recommend removing this note and adding a repeat to (1). Same reason as before regarding the overlap and this eliminate some of it.
00:58:384 (2,3,4) - Just do repeating slider like 00:59:866 (2), not nice to play stack at this approach rate.
01:02:829 (1) - Snap this to 0.8x distant snapping.01:03:569 (2) - This slider is begging to be curve
http://puu.sh/i7Ma.
01:05:792 (3,4,5) - Repeating slider, you should know why I suggest doing this (5 hit circles in a row is not nice to play at this approach rate).
01:09:495 (3) - Nicer if you try some slider shape for this.
01:14:681 (1,2) - I highly recommend a repeating slider (begin on 1, repeat on the white tick between the two hit circles and ends at 2). Main reason is after a space, it's hard to get the feel of the rhythm again and you need to time your hit precisely for a hit circle while not so much for a slider. Also since two hit circles like this suggests there is nothing between the two notes while I can clearly hear stuff going on there so nicer to have some hitsound on it.
01:15:792 (x) - I'm not sure how hard your normal is, but I would do a repeating slider here too (repeat on 1, ends on 2).
01:16:903 (5) - Experiment with red point (double click a white point two times) to accent some of the vocal/instrument since a plain straight slider doesn't represent the feel very well at all for me.
01:20:607 (3) - ^
01:28:755 (2) - Recommend a slider and end it on 01:29:125 to follow the vocal here more.
01:29:495 (3,4,5) - Recommend a repeating slider to avoid some of the ugly overlaps.
01:31:718 (2) - Try red points etc.
You didn't map the rest?
This is a must. Think of it this way, I'm a beginner at this game, I saw this song and try the easiest diff. I find it too easy. I try the next diff and was surprised by how the map goes on for an extra 2 mins and eventually got too tired and fail this diff, not too nice for difficulty spread imo.
[
Normal]
-A bit tired to mention some of the same stuff, but I recommend try to use red points/curve/do slider shape for your sliders and mix some slider for some of the part you use lots of hit circle.I will take a quick look through, but remember, like at the beginning, I didn't mention about the hit circles, but I recommend using more slider for this part.
00:26:347 (4,5,6) - Repeating slider to avoid overlap.
00:32:458 (4,5,6) - ^
00:50:051 (1,2,3,4,5,6) - You should focus on vocal and not instrument here, use some sliders. This pattern look like something that should be in hard/insane (stream).
00:51:718 (1) - This long slider is weird considering what you did for the previous part, should be map out.
00:54:495 (4) - ^
01:01:162 (3,4,5) - Repeating slider 01:01:903 (6,7,8) - Repeating slider. Similar feel but looks a lot cleaner and nicer to play.
01:10:051 (3) - You don't need this note, play just fine without it.
01:14:681 (1) - I find this interesting actually, but I find it weird you didn't do this in Easy actually. Hmm...it's not a problem I guess.
01:20:607 (5) - Try to avoid kick sliders (repeating slider with more than on repeat), you cannot know how many repeats a repeating slider is going to have and especially for the easier diff, beginners shouldn't have to think "Oh no! A repeating slider, I wonder how many repeats this is going to have" and instead enjoy the patterns. I suggest removing a repeat and add a hit circle instead. Then do slider for 01:22:088 (1,2).
01:34:866 (5,6,7) - Repeating slider, avoid overlap.
01:47:644 (2) - Again, I find these long sliders more suitable for an Easy.
01:56:718 (4,5,1,2) - To be honest, it plays fine and doesn't look that bad but I prefer if you do short sliders instead.
01:59:125 (5) - This is where I would expect a long slider actually. Another problem is this is a kick slider.
02:02:088 (2) - ^
02:04:125 (1,2,3,4) - Just do a slider starting on (1) and ending on (4).
02:07:273 (1,2,3) - Definitely consider repeating slider and for all similar pattern.
02:19:125 (2) - Please curve it, the song feel isn't really straight to me.
02:21:347 (5) - ^
Slider speed change is not recommend for Easy & Normal. This is because beginner normally read spacing and when slider velocity change, so does the spacing. I recommend removing it, but if you want to keep it, please use 0.75x. This is too much and make slider really too slow.
02:31:718 (1) - I feel like saying use tick rate 1 due to how many slider ticks this have. Note: For previous parts with lot of hitcircle, please use some long sliders instead, the amount of hit circle make this part feel really intense while the song is a lot calmer here.
02:39:125 (1,3) - Curve
02:46:162 - 03:05:421 - You use too many hit circles. If you are curious why I find this a bad thing, take a look at most recently ranked map. There are never this many hit circles in a row and this song doesn't feel like this as well.
Should be map to the same spot as Insane for difficulty spread. Hmm... my best suggestion is to look at recently ranked map and see what they do. Some people don't want to do this, but this is honestly the best way other than to "map more."
I'm really too tired to mod anymore now, almost 5am. Took a quick look at Hard, Insane and guest diff.
Hard & Insane & guest diff
I find the long sliders quite weird when I can hear something playing during the middle of them. And same issue with lot of hit circles for parts which aren't really so.
SinDemon's Insane
I find the breaks really weird and breaks the flow, and definitely look at those long slider, I'm curious at why you didn't map them out.
The key to making your beatmap better is to mix slider and hit circle better and control when you use some of those long sliders. Be sure to keep working on it, self mod is key. Modding can only do so much, what you try to fix yourself is worth more than 100s of mod post imo.
Definitely take a look at the ranked map with Hatsune Miku singing this song. I see some nice idea in it (not all of the ideas are good through imo) and you should apply some to your map. Don't consider this as copying, but a nice way to learn what works and what doesn't. Well that's all from me. Sorry if lot of suggestion has to do with my preference (I prefer using sliders for most of my maps).
Edits: Fix some errors in post, so tired that I was repeating some stuff and spelling words wrong
