well, the 3/4 quarter drawing is good...but the roof on the front and ESPECIALLY THE BACK are majorly distorted. That has to be one of your biggest problems. Also, it is too scrunched to be a real car, unless it is supposed to be a compact supercar, with the emphasis on compact, give it some more length...It looks kinda cartoony, also...

great effort,mate. keep your drawing going. and going. do not ever give up, just like winston churchill said. never ever give up.

buy a model of a skyline or something that you like as an import-tuner car and draw the living heL out of it. learn PROPORTION. then you can break the rules.

you have imagination and talent and that is obvious from your sketches.

It looks straight to me. Nice scetch and I like the car itself.
