crazy 989, you're right about the windshield/rearshield/side windows. I forgot to give some depth, so the computation of refraction was completely biased. Below is a render with a proper thickness (3mm) and correct IOR (~1.52)
Icekid84, I really agree with you. Even the most interesting car becomes boring when you've see a few WIPs for it. I think I will really stick to rare cars, like my recent projects : RenaultSport Spider, Aston DB9, Ariel Atom etc.
greenvampire, thanks !
tiberius, I've made the following color tests. Feel free to say the one you prefer.
fskpzns, thanks, but it's far from being completed. Stay tuned
Erik_S, thanks. You're the very first one to rate my work, so I really appreciate.
Here are some renders showing different renders. The tire is now modeled, but it's not clearly visible from that point of view.
The last color is the one I used for first modeling of the car, trying to mimic the color of the car presented in the SportAuto review. So the name.
