Nice work, BUT! There's a mismatch on the right side of the car where the front wheel panel meets the front bumper (visible on cmx preview). Gray part on the front bumper is a few pixels higher than needed. The problem seems to be on the front bumper, because below the gray part there is also a black line, so I assume you shifted that up by mistake. Left side of the car, perfect fit, but fix the right side of the front bumper.
Otherwise good work, and cool render too!
edit: the skin files seem to be correct, maybe you posted a wip preview...
