That's a tasty piece...and yes, nice bitey solo.
The panning of the drums feels odd - it reinforces the repetitive basic pattern - and the kick has more thwack than thud.
The horns could use some EQ shaping to removed the keyboard sound a little from the top end - or adjust the release/sustain.
Your voice and piano are fab.
