I'm guessing since it's been a while since you posted this, you've probably already found someone by now, but I sent you a friend request on Discord anyways x3 Your art looks so cool!
I'm a dev and composer, and if you like my music, I'd love to work with you on this (for free) if you haven't already found someone :3
You can find some of my original soundtracks for my own projects on my YouTube, but I haven't managed to upload everything there yet! I've been wanting to try and compose some stuff for other people's projects for a while now, haha.
Either way, it looks great! Good luck with development ^-^
