I really like the melody that starts at 0:07.
0:50 is awesome too, I like how the melody fits in it.
I think you need a "break", a "pause" somewhere near 1:10, because my ears got bored there. Hopefully you got a cool one at 1:40 =)
This is not my genre (too many synths and things going on, lol), so I can't really give some constructive criticism. But I really enjoyed the final 2:50.
3,5!
