Not bad, reminds me of "Star wars" bar theme somehow. Well done

Hey, cool! I'm not sure quiiite what you were going for, but this sounds like a regular band composed a jazz piece. It's not bad, it just could be better. Keep in mind that much of the jazzy sound comes from crazy chords, walking bass, and improv. For crazy chords, there's a lot of techniques out there, but I find that the best chords come out of combinations of circular progressions, modal interchange, secondary dominants, 7ths, 9ths, & so on, and tensions. Oh, and the II-V and it's variations, of course. For coming up with chord progressions when you feel like it, try Online Sequencer ( https://onlinesequencer.net/ ). You can experiment with chords pretty freely there. Good luck! :)
