Great composition and use of instruments. I could really see this in a video game.
Areas to improve: I would suggest looking into the loudness of your mix. Right now it's a little quiet. If you need some way to measure loudness, try Youlean Loudness Meter. There is a free version so no worries there. Without going too much into detail, a safe number to aim for is around -14 LUFS.
Awesome work! I hope to hear more from you! :)
