Excellent work. The front looks like it extends out a tad bit too far (by maybe a stud or so, but you used those curved bricks, so I can understand why. Also, I noticed your stop sign doesn't look like it can fold out. I'd suggest checking out your hinge pieces for that one. Other than those minor things this is a really great bus, packed full of detail. You've even got the little mirrors on the hood of the bus.
