I've made my own design of a sports car with a decent amount of detail and with a bunch of node setups for the different materials ^^ this is my very first upload btw .. hope you all like it :D ITS RIGGED AS WELL HUHU
I think there has to be some details as trunk, hood, doors etc. But the overall shape of the car looks nice and clean so try to add these...
how to change color of the car
I guess you did not use blender for texturing. did you use substance painter?
