Excellent!
I really dug this! You've got some excellent slow buildups in here, which does make for a pretty "epic" track. When that tom driven beat came in @ about 1:30 this really started rocking. The layering of all this different synths at the end worked great as well!
My only criticism would be concerning the overall production quality of the track, there seems to be a lot of clipping from cranking things up just a notch to high in the volume department, takes a little of the impact of the beats away and causes some "bad" distortion, but it certainly didn't keep me from enjoying this!
Keep up the solid work!
