Reminds me of Castlevania music
tl;dr first: I enjoyed it. It was something that sounded like I was playing some of the side scrolling castlevania games (mainly belmonts theme). Although it was pretty simple, I think that this would go perfectly with your collab. The parts that I would fix is to make the backround a bit emersive and kind of envelope the listener with melody/harmony.
Actually, for once, that's really all I can say, I am feeling really tired right now so there isn't much else to say other than good job. You should consider doing more music in the future, maybe then I'll be more awake and give better feedback. Anyway, good job, hope to hear more from you mate.
Till next time
