Overall, it's pretty good. sounds are not brickwalling, which is always a plus in my book lol. The mix seems like it needs a little work though. the bass is a little bit loud and seems to pretty much drown out that lead Saw synth you have. that build at 3:30 seems a little empty, maybe try adding some light percussion, like a cool break or something.
other than those few things, this seems to be coming along quite nicely!
this gets a rating of 4/5, and 3.5 stars outa 5 stars from me.
