Nice arrangment
The performance seems to be pretty rockin' too - just too bad the recording quality is shit (I'm almost hearing as much distortion as I am the instruments). I doubt you can fix this just be tweaking the levels; unless you've completely fucked this mix, it's more likely that the original recordings of the instruments were really messed up. You'd really need to rerecording this to get it sounding presentable - I'd also add some another repeat or two with variations to get it at a better length, as the ending feels really abrupt in this one. Still, it sounds like you guys really have potential though - don't let it go waste.
