Your snare needs more punch and probably some more high-end - it kind of has a nice character to it so I'd think about layering it, but it might be better to look for a different sample. Your kick sounds very boomy - it has a long tail on it that almost sounds like reverb.
That little vocal sample (if that's what it is): I like the shorter version of it (e.g. at 0:43) but I'm not totally sold on the longer version - it has a kind of weird breathiness to it.
This is a pretty cool tune though, I like whatever that melodic sample is you have running through it
