Wicked tune....
This is a good tune, but I think it could be improved drastically in a couple of areas. I think it would really benefit with a beefier kick. If I were you, i'd try and really boost the lower frequencies of your kick, just to make it more punchy.
Also, i'd make the bass more predominant in the mix, I think it could do with being a little louder. These are really the only aspects where I could offer possible improvement. Everything else is tight, especially the rest of the percussion which is amazingly well produced.
Good work man, keep them coming.
