I like the old school nostalgic vibe here. I also like that you played your instrument, delivering natural dynamics. I strongly encourage people to do that because its so much better than trying to key in all the dynamics in a midi scoring system, which is slow and tedious.
Constructive feedback:
While I encourage people to improvise a lot - to my ear, this sounds like pure improvisation, and maybe like it isn't tied together in a way that is maybe as cohesive as it could be overall. I say this because I do a lot of this sort of wandering improvising as a form of practice and discovering ideas, so I'm sensitive to that pattern. Not sure if that's what you did here, but it's kind of what it sounds like to me.
That said, as it goes, it is good improvisation/playing, with good articulation, dynamics, and keeping a sense of place and story.
Great work, thank you for joining!
