Wish I played that well out of HS. You've got a fairly solid tone and know your way around the sax. You don't sound too tentative which generally equates to confidence. These are all good qualities that will be the foundation on which you can build.
What needs work (IMHO) is to be communicating something more personal through your horn. It's not just about tone and playing the right notes. The sax has the greatest potential to communicate of any instrument other than the human voice. This comes through subtleties of dynamics, phrasing, and variations in tonal qualities, like a human voice. Only wind instrument players can do this easily and effectively.
Your playing (although technically correct) wasn't much different than the guitarist (who also lacked feeling). By contrast the bass player communicated much more in his playing. This is like being out-run by a guy with one leg. Try singing what you have played, but NOT trying to sing AS YOU HAVE PLAYED IT. Listen to how different your phrasing, slurs, attacks etc. are. When intensively learning and practicing an instrument, being technically correct/accurate becomes the emphasis at the expense of personal expression. No need to unlearn anything though, just time to add to what you have learned and express yourself.
What you have plus some feeling and expression will make you a killer.
