Thats FUN bro! Might just have to drop that in a mix one night...
I like the tight sub/kick when the main beat comes in first, nice production. The bass guitar sounds a wee bit thin, tho, and could be taken further in choppage or variations IMHO.
Watch out for over-compression or limiting when the drums kick in at 30sec and again at 1.45, it kills the volume on the off-beat guitar/keys which are the defining element for ska. I think the track works best when its ska with a spicy sprinkle of DnB, rather than the other way round. but thats just me.
Probably more than you wanted, but there you go...
peace
