Hi Mark, on a quick listen on Soundclick to my ears the kick/ sub @35-40 hz. is too much. I think you might try lowering the whole drum track 2-3 db as the high end on it seems a bit hot too. Also try boosting the bass 400hz- 800hz a tad.
Grain of salt I'd use either the drum stick or Side Stick but not both & alternating them as you're doing & simplify the part a bit (might try brushes too if you haven't already.)
Great tune, enjoyed it. Nice warm vibe I think you just need to dial in the drums a bit..
