Its not horrible but it could be better. I think you should continue to work on your skills as they can only get better you know. Im not an expert at that im more into music of course but just an opinion with some constructive criticism. Keep Working yo

It's not bad I dont really like the singing though lol. I mean as far as from me being a music producer for a variety of different artists the humming unless it was meant to be comical isn't that great. It could be better it sounds like they might have a voice on them if they managed it better and like went up and down in the vocals rather than just humming that "oooooohhhhhhhhh". Keep working though it can only get better!
