Wow...
You've improved, haven't you? :) This is a very nice track. I think the background sound kind of fits, though. It sounds a little too short though. Think of new melodies & beats & it'd be a LOT better. The bass you used sound very good. The lead synth, though, sound like you could change it.
Please check my Audio Page, too, when you have the time & review my newest track, "Your End Remix [D]".
