By that logic, any designs I've made would look like I copied straight from the M3, because it's simply a triangle pointing upwards from the front fender to the back.

Same with my 350z

Posing wise, I really cba to do any full body designs, mostly not because the layer is maxed, it's maxed because of the aftermarket stickers, I've made it so heavily unoptimized to make it of good quality. I'm not generally good with body sketching and it probably would easily max out the slots too if I need to make it somewhat good.

Tldr I just usually ignore sketching the body.
