I love the general vibe of the beat my dude.
When that saxophone came in, ooooooo.
However, IMO -- the snare ruined the smooth vibe of the sax / piano.
I think this is mainly because of how loud it is. I don't think the reverb sound is wrong, just compress it more and make it fit more with the whole track.
As far as the hook, the vocal chops are great! I would suggest maybe altering some synth sounds, they almost sound too generic at parts, then overall mixing everything down more cohesively.
Sorry that was so extensive... BUT I love the track. Add a few tweaks and this could be an amazing joint.
