First off I'll point out some basic things I know, because I think that will be most helpful to both the map and your own improvement in mapping.
You can use AiMod to point out basic problems with your map. Go to file and press "open AiMod"
The filesize is too large because of the video, it should be under 24mb.
Use distance snap for low star rating maps.
If you're making blankets do it properly, or else it looks really bad.
Uneven accidental overlaps looks pretty bad
Repeating patterns for the same sounds is good, but do not just copy paste and forget about changing it.
Work on making better looking sliders.
t/208596 and
t/37194Prioritize an instrument, and let other sounds be secondary,
For such a low star rating, the map should help showing where the next note is, not hide it. If a slider goes to the right, you should not put the next note on the left of it. I drew the flow for the part at 01:05:310 (2,3,4,5) -
00:21:674 (1) - This spinner is very long, for new players this is uncomfortable to do. consider halving it
00:28:024 (1) - Boring slider, doesn't feel like it fits.
00:28:681 (2,3,4) - Uneven and random, maybe try doing something like this
00:30:433 (5) - There's no sound for the repeating slider to end on, make it normal slider.
00:31:309 (7) - You're ignoring the downbeat (big white tick), I would not prioritize vocals.
00:32:404 (1,2,3,4) - Why not continue the circular motion with the circles?
00:36:127 (7) - Not mapped to anything.
00:36:346 (8) - Slider head should be on a stronger or equal sound as the slider tail, This would be better
00:43:572 (3) - Same as above but this time the slider head isn't even mapped to anything.
00:44:667 (1) - There's no sound for this slider on the red ticks, use circles on the white ticks instead
00:46:857 (2) - Not mapped to anything
00:48:608 (3) - Maybe use circles instead here on slider head and slider end. sound on downbeat is more prominent.
00:52:112 (8) - Away with the repeating and make it a full beat slider (white tick to white tick) or use circles.
00:53:426 (9) - Remove repeat, no sound.
00:54:083 (10) - Remove this, there's no notes for it.
00:55:237 (2) - Remove repeat, slider head should be on the stronger sound.
01:00:493 (3,1,2) - Bad overlapping, and uneven spacing on (1) between the sliders
01:08:157 (3,4) - What sounds are these mapped to?
01:08:814 (5,6,7) - 5 and 6 aren't mapped to anything, the vocal syllables starts on the blue ticks in 1/4. mapping to the blue tick when most of the map wouldn't be good either unless you do it correctly, watch this video on polarity
https://www.youtube.com/watch?v=53PkFLrK8WsI would do this instead
01:21:515 (1) - avoid using repeating sliders like this in low star rating, it's too quick for a new player to see that it will continue repeating. It also ends on a stronger note anyway
01:25:237 (2) - Not mapped to anything
I Modded until the first chorus ended, so you can figure out for yourself these problems in the rest of the map. I just chose the most important things you need to learn.
You should watch pishifat's videos on youtube about mapping, they will tell you a lot more detailed stuff.
https://www.youtube.com/user/PishifatWhile you have the chance, practice on responding to mods. Respond to each point with a color so your response is distinguishable.
Continue mapping and you will for sure get better! Good luck
