I like the tune. Nice melody, nice bridge, nice groove.
Here's my criticism:
-Bass is just a little low in the mix. It's there (definitely not too bad), but not with the presence it should be.
-I understand if you layered sounds for the melody, but it makes it sound (to my ears) like two flutes playing in unison the whole time -and unison is a very heavy, monotonous sound. I would have them split on the second A section into harmony -even something simple like thirds would totally enhance what's going on.
-This is begging for some more right hand comping from the piano. You've got that great written part on the A sections, but when it gets to the bridge (actually a C section I think?) the piano should be answering the melody (something improvised). After all, there are only a couple chords. Feeding us that harmony again is unnecessary. Instead giving us melodic information pulls our ear toward the next section.
Very good work -keep it up!
