Hey! I listened to your WiP, it doesn't match the quality bar we're looking for, sorry. It is still a good first try! As Brandon said, you should keep practicing and ask for feedback to people in the Workshop forums, they are there for that!
Also: We're still recruiting and we allow two different takes on the same track, even if it's already claimed by someone else. So, don't hesitate to ask for it. Medleys are still welcome too!
