Nice.
Good pace too, stompin tempo.
Production overall is very clean, good separation.
I don`t think it needs more dirt at all.
People forget what happens to sound on a soundsystem and overcompensate on noise at home when making this kind of music, trying to reproduce the loud system effect.
Too dirty and it sounds shit on a rig.
This will translate well to a soundsystem and still rawk nicely.

I found the mix a little too static, and lacking presence and polish overall.
I think the hats are a little too crisp and thin, and could do with just a little verb and maybe some back up in the lower regions of the top end (if that makes sense). Somewhere around 2.5k-ish just to add a bit of warmth.

The bass could be just a little meatier too.
The lead sound (the grungey one) that comes in could be much larger.
I`d really expand it stereo wise, and maybe get some very subtle fx in the back of it, just to give it a little sheen (maybe some chorus)

I`d go back and work my way through the sounds polishing a little, giving the lead sounds more presence, adding touches of verb here and there, maybe using some higher quality EQ`s on the more important sounds, better compression etc.

Good stuff, and it`s nice to hear good controlled production, but basically you just need to get out your mister sheen and polish polish polish.
