I really like the B section and I think it is really cool
Good start:) Few things: I'd cut the intro at the beginning because it doesn't sound anything like your A section. Each of your sections worked out alright, but they all sounded like they had a ton of mini sections within each section. I'd try editing your B and C sections first, they are longer. Pick the sounds you like the BEST from those sections and make them longer, cutting the unnecessary parts. See how this goes for you, editing can be tough! See me if you need help. Good luck!
