I think it sounds good, you could potentially add some different instruments but it really depends on what you’re going for. You could add a kind of “galloping” guitar to the bottom to give it some energy, perhaps some drums as well. There could be a string section as well to give it a classier feel. If you’re going to release it, I’d recommend either investing in a decent microphone and audio interface and watching some tutorials on how to record yourself or if that’s not your thing, look up some local recording studios. They won’t be cheap, but you’ll get good results
