This is cool! The mix sounds decent to me btw, but I'll try to focus more on the composition.
I overall like the composition, but I'll be nitpicky for you. There are lots of cool elements, and for the most part there are pieces that glue the sections together. One thing I think it would benefit from is a melody. You've got the high lead line that's very "note-y" -- and it's cool and it gives it that jazz feel you're talking about -- but it's maybe too note-y to be the main melody. Y'know, it doesn't hook me or stick in my head once the song is over. You could maybe take one of the sections, remove some of the notes from that line until it sounds melodic..? It depends what you're going for, but I'd personally try something like that.
I really like the buildup to 2:35, but it'd be great if the drop were more intense! Maybe some of those loud saw pads layered in, to make that part stand out from previous sections? Something to try.
Let me know if you have any specific questions and I'll do my best to get back to you. Nice work, I really like the sound of it!
