Very nice!
First off, I don't talk too much about the good parts when criticising, for various reasons. So don't get upset if I (or others who share my mentality) only talk about the bad parts
I don't know much about jazz, I'm mainly a classical pianist. However, it sounds like the drums are too repetitive. And there might be a bit more room for development in terms of variation. Perhaps give the bass a solo, with the piano providing a chord or two every chord change?
