nah i like the volume ducks you have, goes with the funk. in terms of the shuffle, maybe a light shuffle right when the piano riff comes in with the stabs.
I agree bout the dry piano, id do a slight delay send and some thin reverb with wide stereo. Id like to hear some stopping and glitching syncopated with the drums, a little like you have going around 2min in but more sudden and sidechained to the kick. just imho
good work mate
