I'm no fan of The Template, but get some other opinion on whether you have applied it correctly. The top view Template[s] are complete, but the side view is butchered. The ground plane and
departure angle have been deleted. What you have is suitable for off-road rock crawling. IMHO it should also slide forward to match the contour at the roof.
I know you're fixated on reducing down to the height, if not width of a license plate. You're compromising a lot to get there.
