The chop looks great! I definitely see a huge improvement compared to your last couple chops.
A small tip: although stickers are just "stickers", they too, need a lot of attention.
1) never have (or at least avoid) stickers / logos on door lines or trim lines. Having a company's logo cut off or sliced in half is unpleasing.
2) have a hierarchy of logos. Arrange your logos with primary and secondary in mind. Primary is the main, big logo on the side of a car, and it may recall numerous times on the body. Secondary logos are the smaller ones, usually as a list of sponsors on the door (roll calling)
oh and your copyright isnt working very well there
Logo placement is a design of its own, and its very important for sponsor cars. Graphic design skills come in useful here!
Have a look at the Crawford tC i worked on. Everything on the car was strategically placed:
