Normal:
- 02:27:913 (4) - Break after this? Unless you wanted the hp drain to go down and for the player to pick it up.
- 03:06:485 (1) - I think using whistles from here to the end sounds nice.

Dream End:
- 01:01:342 (1,2,3,4,5,6,7) - The placement looks really random. Maybe change it up a bit.
- 01:08:842 - Having nothing here breaks the flow. Maybe add a note here with whistle or change the previous pattern up a bit.
- 01:10:770 (1,2,3,4,5) - I think it sounds better if u follow the previous hitsound pattern. Whistle on 1, 4, and the end of 5.
- 01:58:127 (1) to 02:01:342 (4) - The beat placement looks really ugly here, like you just placed them anywhere.
- 02:28:770 (1) to 02:31:770 (13) - ^
- 02:56:413 (2,4,6,8) - Make these aligned like 1,3,5,7. Plays better imo. http://osu.ppy.sh/ss/434799
- 02:59:627 (1) to 03:11:199 (8) - Not sure if this was intentional, but the patterns just go in a circle during this part. I never thought excessive circle patterns were that interesting. This is just my opinion though, you might really like going in a circle like this.
- 03:17:413 (1) to 03:20:306 (1) - Beat placement looks random again.
