Nice tune, drum sounds don't fit it at all. The snare is a bit too crisp/bright/punchy. A more natural sounding sample with a bit more decay would probably help. Actually, I feel like the drum pattern itself probably needs more swing; it sounds like you've got a great bluesy band going and some uptight substitute drummer sitting in killing the groove. The snare fill parts are in the right direction; kick part is too static and straight though. Melodies and whatnot are very nice though, they definitely have that blues feel.
