At least it was in tune, for the most part...
...I'm not really sure what else to say, or not say.
I take it you're young, or just starting out, which would explain why you didn't follow the changes during your solo. But you stayed pretty safe in the realm of the pentatonic, so I guess I should hand it to you for not trying to reach too far past your limits. I realize that this was a practice session, but theres almost no reason to practice your "foot in the bell" low A, because you'll never use it in practical situations--I've only seen it written in a couple of Rob McConnell charts purposely, and only then for effect, and I can't think of any alto players who seriously try to go that far down on the horn.
Bravo to you, though, for putting this out there for the world to hear and criticize. Takes guts
Keep practicing, and it will come together. Good luck.
