I actually composed my own theme song for my comic! Here it is!
The mastering and synths are a bit dated and I plan on remastering it and stuff later on, since I've gotten better with EQ and have updated my arsenal of instruments since making this.
Being a musician, I make a lot of soundtrack for my own comic, and even my friend Eternal Sushi has composed a few tracks for it. I recommend checking him out, by the way! He does art-music trades.
