Well you sure don't sound like a beginner to me! Good feel in your playing and phrasing. You've got good control over your slurs and use them well, and I think could use them more. OK, the constructive criticism stuff (to work on?): Wide vibrato, which is OK, but needs consistency. It seems like you avoid holding long notes for this reason? Bottom of the horn sounds flat. This may be due to tuning for the upper and using a lot of embouchure pressure? Try tuning up slightly so that the bottom of the horn is in tune and relaxing your embouchure for the higher notes (a different mouthpiece or reed strength could help). I haven't heard you play other things, so it may be that you're just using a flurry of approach notes for this particular tune, however it can be a bit much. You've got good feeling and phrasing, I'd go for squeezing more emotion into it with longer tones rather than a lot of decorative notes that mean little and can eventually be "clutter".
Most people here just say "that was nice" or something similar, but I hear real talent in your playing. It's more than just notes. Too many players think stuffing a lot more notes in = better player. If you're trying to impress other sax players that might be true. If you're playing to an audience then the story and emotional content is what communicates.
