This is gorgeous.
My main critique would just be that some of the tracks didn't have as high of a quality as the others, and that some of the time for the sake of this jam might have been better spent focusing on the places where you're already very very strong, especially that first track. I was sold on that first track, where it has that sort of Baroque sound to it. I would have just made that a 5 minute long piece and called it a jam, that one really slaps. If you don't listen to a lot of Baroque music, you really should, especially things like Cantatas.
So, being a lover of that style of music, I'm going to offer a more high level critique, where the work you did is already very good. This part of the track really calls for some development because it is very good.
What I really want to hear out of the development in this track is like at 0:28, I would do a build up, and then come in an octave higher with more development and harmony, and keep building the track up to a climax.
Another thing I'm working on doing is getting into partimenti. This is a method of Baroque improvisation. I'm not far along in this process, but I can absolutely tell you that if you can manage to study this, it will complement your style incredibly well. It's essentially an improvisation framework that has positions, rather than progressions.
Here's some more inspiration:
There's a lot going on here for sure.
Very awesome work overall.
