Okay, here's my take as a jazz man myself: There's some really cool stuff, but, dare I say, it lacks enough harmonic structure. The only part that felt a little more coherant to me was when you brought in the kick drum in the drumset and whatever else there was at 1:03 and on. Then I actually started to enjoy it a lot more. My advice would be to make it a little less hectic in the beginning and build to that section because if you listen to jazz songs in a similar style, you'll find they usually build... usually. At 2:02, again, it got a little better.
Your sustained chords you land on are great, but in between it's just too busy....
Really, I like what you did, it just needs to be a little more coherant.
Great job!
