Fregin Sweet!
Except for one mishap'. The volume is shifing to loud and then soft at about 00:37, 00:43, etc.
also, drums are a bit too loud starting at 2:24. im not sure if the effect from the compressor at that part was intentional or not.
other than that, the instruments were amazing! the mixing in the dubsteppy part was pretty great too except for what said above. Nice Job!
one more thing, might i suggest the "30 minutes to a better mix" series on youtube. this guy has some killer mixing techneques and tricks.
