the design is too basic. what is the token for? where would the token go? add some highlights n shadows to the unicycle. if its gonna be called "pimp my ride," y not go big and put a rim on it and make it golden? the blue and white combo reminds me of handicapped signs, which i'm sure was not your intention. those are my thoughts, take what you may.
if its supposed to be a ride, then have it on a stand, with a little slot next to it for the quarrters. also, maybe use a font tat would imply carnival game, etc. just an idea.
