You did very well!
My 'musicular grammar' isn't that good, so i'll tell you the seconds I enjoyed best =)
00:29 "slow and silent to hard and loud"-breaks always get me!
00:57 it also works the other way round
01:13 breaks breaks breaks
01:41 very nice turn, without much contrast this time
01:55 what's that? it gets hard but stays soft?
02:12 yeah! now the chopped sounds start! always hot when not overdone!
02:23 making a silent break before getting hard again is awesome! (no sexual reference intended)
02:52 another nice loud->soft without much contrast!
The action is very nice, the track is very nice. Thank god it's so diverse too!
This music makes me fanboy-ish. More plz!
