Hey, I saw your map on discord. I'm pretty new to mapping so take what I say with a grain of salt.
OverallMany patterns are awkward to play as they don't flow well. Watch this
https://youtu.be/ig7nTSbWwVcThere's a lot of stuff that just isn't that aesthetically pleasing. Spend some time just messing around making sliders. Video on aesthetics:
https://youtu.be/FCB5rLXqWKYNormal 00:09:176 (2) - I feel like there's no beat behind this note. Try a repeating slider for the drums?
00:09:776 (3,4) - I don't like these sliders. Use only 1 control point for a perfect curve.
00:12:776 (2) - This slider should be blanketing the circle before it, just makes it more nice looking.
00:15:176 (2,3) - Same thing, make the sliders look better.
00:17:126 (4,5) - The circle should follow the slider's path, right now it looks out of place when followed by the repeating slider.
00:17:876 (1) - Not a fan of the spinner here. Maybe make it longer?
00:20:576 (3,4) - Maybe make these sliders curve less so they flow into each other?
00:22:226 (2,3) - This slider should be blanketing the circle after it.
00:26:576 (1) - Nothing really wrong here, but consider having the slider blanket the end of the slider before it.
00:27:776 (2,1) - Blanket.
00:43:376 (1,2) - These sliders are just kinda boring, use red control points.
01:16:976 (1,2,3) - ^
01:21:776 (1,2,3) - ^
01:25:976 (2,1) - Blanket.
01:32:126 (1,2) - This slider is pretty nice. Though consider having it blanket the circle after it.
01:42:026 (2) - I really don't like this slider. Maybe try another shape.
02:12:776 (2,3,4) - These slider should flow into each other.
02:42:326 (4,5) - Might be a bit too difficult to read for new players, but don't take my word.
02:44:426 (2,3) - Blanket.
02:46:826 (2) - Not a fan of this slider.
03:02:576 (1,2,3,4,1,2,3) - Avoid having things completely horizontal. Rotate it just a little to make it look better.
Insane00:00:176 (1,2,3,4,5,6,7,8) - Grid mapping doesn't look too great. I also don't see why there are sliders, as there are no beats on the slider ends.
00:13:676 (6,7,8,9,10) - This spacing feels random.
00:15:476 (4,5,6,7,8,9,10,11,12,13) - Patterns feel random and don't flow nicely.
00:19:526 (2) - Not a fan of this slider.
00:25:076 (5,6,7,8,9,10,11,12,13) - Patterns feel random.
00:27:026 (4,5) - Why the change in spacing?
00:27:926 (8,9,10,11,12,13) - Patterns feel random and don't flow nicely.
00:29:876 (5,6,7,8,9,10) - ^
00:31:976 (3,4,5,6) - ^
00:35:126 (9,10,11,12) - ^
00:38:576 (1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7,8,9,10,11,12) - This part just feels a bit messy.
00:43:376 (1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6) - ^
00:48:176 (1,2,3,4,5,6) - Inconsistent spacing.
00:52:076 (7,8,9,10,11,12) - Awkward pattern.
01:06:326 (8,9,10,11,12,13) - ^
01:08:576 (7,8,9,10) - ^
01:14:276 (13,1) - I don't like this overlap.
01:17:726 (4,5,6) - Inconsistent spacing.
01:20:726 (8,9,10,11,12) - Awkward pattern.
01:48:176 (2,3,4) - Boring sliders.
01:50:576 (1,2,3) - ^
02:01:226 (8,1,2,3,4,5) - Make this a proper star.
02:30:026 (4,5,6) - This is not the type of map to have this kind pattern, it looks out of place.
02:40:976 (1,2,3) - Boring sliders.
03:04:676 (11,12) - Make these shorter. The player might get 100s.
03:06:776 (6,7,8,9,10,11,12) - This stream looks awkward. Use ctrl+f to convert a slider into a stream.
03:37:826 (6) - High SV repeating sliders are a bad idea.
04:11:076 (4,5,6,7,8,9,10,11,12,13,14,15,1) - Awkward stream.
There are a lot of notes that overlap for seemingly no reason, unless I missed something.
I didn't go through every pattern, but the vast majority were awkward.
Hope I helped.
