Ill point the problems

first problem
no real melody (which every song needs... really it does)

second
some of the transissions didn't really work that first part where you completely got rid of the first synth and replaced it that shouldn't of happened instead have those two track play in unison (if you know what i mean)

Third
Drum beats. most have this problem the drum beats were stale and needed more reverb added to it so it sounded open like the other synths

other than that... not bad
