Recorded this a while back, very interested on learning to improvise well and become a better saxophonist. I want to hear your suggestions, tips, advice and comments on my playing. I've been playing approximately 4-5 years (concert and marching band).

My setup:
Selmer Aristocrat AS600
Otto Link super tone master 5*

The improv is a solo i recorded with just the main lick established, the rest came up as i went on. Please do comment, suggest, critic, and give your opinion, very much appreciate it. Thanks in advance!
