There were a few things easily fixed in Photoshop with the classic rebodied Miata earlier today. The front jowls initially bugged the heck out of me, but looking at the rest of the car, there were a few things to tune. Body is too slab sided, needs to roll under more and lift off the ground for classic lightness impression. Roof mass is too flat- needs volume to match rest of the car and give meat to the area above the windshield header. Is the lower image an improvement? What do you think?
Long dash-to-axle is a great proportion to work with, but that big empty space between the from wheelhouse and doorcut needs a garnish, trim piece or air outlet to entertain the eye.
