Well the refs on the hood match the background and im not going for any drastic colour changes so probably just door and rear arch. Which is near enough the whole body anyway
Wheels are still well well off. The rear should be a thinner ellipse ( as in we see less of what's actually in the rim). Take wheels from a donor at the same angle. And as ATC said, it'll look better with either larger arches or a tad higher off the ground so the wheels actually fit.
