Hey, from your M4M.
GENERAL
Combo Colours - Add some grey-scale to your colours. Right now 1 and 3 are way too bright.
Background - I know it's been pointed out, but I'm fairly confident that having a non-standard resolution for your background (stretched) IS un-rankable and it needs to be changed. The easiest is 1366x768. There are a couple other acceptable resolutions but for this picture that would work best, try to get it re-sized or look for one already sized to those dimensions.
EASY
Sliders - Not going to give a time signature, in general the slider shapes in this map are not very nice looking, Try making them either a little less sharp, or make it a harsh corner instead of being a curve with a pinched edge.
Volume - Is it deliberate that the first 10 seconds are at 40% volume while the rest is at 30%? Seems pretty random if it was....
Combo - The NC in this map, while it roughly follows patterns that's not always true, and it doesn't follow a specific time signature either, I'd recommend for simplicity sake redo the NC in the map to "NC every 2 measures (every second large white tick) regardless of the current pattern or combo length.
00:06:470 - (4,5) This pattern involves crossing over an already established slider path which is something I don't like to see in Easy diffs, I'd recommend lowering the 4 slider and rotating it counter-clockwise a little bit to open up the flow path it follows.
00:11:243 - (1,2,3,1,2,1) This entire segment has slightly broken DS. when going for consistency having DS that differs by 0.02 or even 0.03 in either direction is acceptable, but 0.09-0.10 is out of acceptable range, If you need to make the distances exact it's easier to disable grid snapping to make placements perfect.
00:31:016 - (1,1,1,1,1,1) IMO you spend far too long here just having full measure sliders, six in a row, at 88 BPM, which is already slow. Even by Easy standards I would find this incredibly boring, Try to change it. Map it to another track or make shorter sliders, something along those lines.
01:27:606 - (2,3,4) For some reason the spacing isn't the same for these three and it looks weird, make them spaced exactly the same distance from each other. Also 4 is at y:175 while the other two are at y:176, Line them up.
NORMAL
Combo - Much the same about NC
Sliders - Much of the same about the slider shapes.
Sliders - Now it's possible this has changed, however what I've heard is that in Easy and Normal difficulties sliders that repeat more than a single time are not rankable. I've listed the time-stamps below where these are present.
00:21:470
00:29:652
00:01:016 - (1,2,3) DS break here, Actually, not going to mark every DS break, the entire first section (Until 00:09:197) has some pretty random DS in it, Try to fix.
00:01:016 - This entire beginning is a little bit of a difficulty jump from the last diff, I'd suggest picking a few couples of circles and making them a Slider instead.
00:09:879 - (3) Not sure why there is dead air around this circle, the music is still playing the same as it was before and you didn't skip a beat there. this just feels weird to play as there should be something here.
00:12:947 - (2,3) Not going to point out every instance of this, but this is a square pattern so it shouldn't have a curve to it's movement, make sure these two notes are level with each other.
00:16:016 - (3) This is another strange thing I've seen you do quite a bit. There is a strong beat in this slider that goes unnoticed because the slider just passes over it. Maybe in Easy diffs it's fine but in Normal's at least every STRONG beat should be mapped.
My problems with this diff are many repeated instances of the same things I noted before, As I don't want to post a list of weird shapes, DS breaks, NC inconsistencies and Misaligned notes/Blanket errors. I'm just going to keep to the initial examples I noticed and hopefully you can figure out how to apply that to the rest of the map, If you'd like help I'd be more than happy to clarify positions in game.
HARD
Similar issues with slider shapes and NC consistency. DS isn't as big a deal being a Hard but there's still a couple points which should be changed.
Map-Set - How is it that the beginning segment on the Hard is mapped in an easier way than it's mapped in the Normal? It'd make more sense if you switched the two sections as the Normal is a little too hard while the hard is a little bit easier than the rest of the map is. this isn't an issue but it really stands out when the same segment is easier on the harder difficulty of the same song by the same mapper.
I'm going to stop here, Frankly I'm just noticing a lot of the same and I feel these are some basic things that need to be cleared up before you can really focus on fine-tuning. I see a lot of habits that I used to have when I started mapping so I feel like we're quite similar in that regard. If you need any additional help feel free to contact me later.
