Notation = Good; Instrumentation = (?)
I feel like this belongs in an episode of House. What I'd actually suggest is changing the instruments you're using for the opening lead... sounds like a sort of lame brass synth. The other synth that comes in at 00:34 just doesn't sound all that great either.
The atmosphere you're posing here is quite nice and the notation is superb, but I just feel those instruments chosen contrast it too much. Just an experimental suggestion, try seeing if making the drums at 2:00 hollow sounding like in the intro... maybe it'll sound badass. I dunno. Just a thought.
But yea, that's about as constructive as I can get at this point...
Yeah, I never thought the instruments really fitted together, but every time I tried to change it, I would end up ruining it. I probably didn't try hard enough though.
Thanks for actually bothering to suggest ways to improve it; you know what most people are like on newgrounds.
And House music is pretty cool. I'm flattered :D
Thanks again, man.
