i might be missing something here but how and where can you see my chops??? maybe it is my screen but i don't see anything
^ on the tire u can see where u cut. cuz its really dark on the edge of the tire and really choppy.. the rims look ight its just that outline that throws it off. also when u color them instead of using the brightness, use the Hue/Saturation, turn the saturation all the way to -100 and then use the lightness and turn it down till u get the desired color.. looks better that way.
But on ur chops instead of using the polygon tool to cut, use the pen or ellispe tool(for wheels) and right click and select Make Selection.. the pen tool and shape tools u can make ur chops turn out alot better
