Easy:
I think you should change the distance snap divisor to 0.8 or 0.7, that way you'll achieve much more pattern.
00:29:467 (2,3) - Blanket two into three.
00:32:394 (2,3) - ^
00:39:711 (1,2,1) - Try something like this?

01:47:028 (1) - end this here 01:48:858.

Wings:
Change HP drain to 5 or 4, 6 is way too high (and annoying) for hard.

I have no imagination when it comes to sliders...
You have a really nice SB too, star for this.
