for the 30 seconds it runs, it's pretty good. it's kinda hard to suggest much when it's basically just the intro. for instance, i could say "needs mixing" or "synth work" or something like that (just examples not for real), but i'd have to see where the song ends up (style-wise) before i say anything since i don't want to make u feel you have to change something that you meant it to sound like. btw... do you have a VST acapella software, or do you find and download the vocal tracks?
