00:00:614 (1,2,3,4,5) - You copy-pasted this group of objects 8 times and it's very visible. You should vary both pattern and, to some extent, how you play the rhythm. For instance, both the first two ,and the third and fourth notes could be replaced by a slider each without contradicting the music; that alone gives you four different variations of the rhythm. Put each of them in a row and play around with object placement, and you have a much more interesting entry to your map.
00:15:819 (1,2,4) - These should be lined up properly.
00:16:230 (3,5,6,7) - These look unorganized. You could put 6-7 parallel to 1-2 and lead 3-5 together.
00:21:983 (5) - Weird looking slider. You should probably refine it.
00:25:271 (5) - ^
00:26:915 (7,2) - Stack these.
00:27:737 (2,4,6) - These overlaps look weird. Spread it out more.
00:30:614 (2) - Slidershape not used before, sticks out weirdly.
00:32:668 (3,5) - You could bring these together and blanket 3 with 5.
00:35:134 (5) - Slider.
00:37:189 (1,2,3,4) - These overlaps look unrefined. You should probably spread these out and make the space between them more consistent by offsetting them more.
00:38:422 (1) - A weird slider, this time a different one. Again, you should refine it. Maybe blanket something that comes after it to give it grip within the following pattern.
00:41:093 (4,7) - Weird overlap.
00:42:942 (4,6,3) - You should blanket using both of these. And blanket that with 00:44:175 (3,5) -
00:46:230 (1,3) - Fix overlap + blanket.
00:47:874 (1,3) - Overlap.
00:48:490 (4,1) - Blanket?
00:49:107 (1,3) - Stack or space.
01:02:873 (4,5) - Fix blanket.
01:07:600 (3,2) - Stack or space (maybe blanket with 01:08:833 (3) - )
01:10:682 (3,4) - Overlap.
01:11:504 (1,5) - ^
01:12:942 (8) - You can clean this slider up like this:
01:14:175 (3,2) - Blanket?
01:30:819 (1) - You could make the curves in this look better and possibly blanket something afterwards.
01:40:888 (3,5) - Fix blanket.
01:50:134 (6) - Move this in line with the rest of the pattern.
01:51:161 (3,5,6) - Line these up.
01:54:038 (1,2,4) - ^
01:55:066 (6,1,3) - ^
02:06:983 (4,1) - Blanket.
02:13:353 (3) - Move in line with the rest of the pattern.
02:13:970 (2,4) - Blanket.
02:17:052 (1,4) - ^ Also apparently you know how to do the slider. Do I look condescending for explaining that earlier now? :/
02:25:682 (1) - Blanket.
02:47:257 (6) - Move into the pattern.
02:47:052 (5,1) - Blanket.
03:07:189 (5,1) - ^
03:08:833 (3,4) - Overlap.
03:11:298 (1,2,4) - Line up.
03:12:326 (6) - Slider looks weird.
