Nice, some things i would like to point out are your front wheel looks like it has positive camber, you should rotate it a bit, also the right side wheel is bigger than the left one, i can still see the spoiler from the window, the shadow is a bit off, it looks like your car is floating, now i'm not pro or anything but with all that rust, i don't think your car should have relfections, like i still see reflections on the hood and the back fender, this bg looks a bit "darky" so i don't think your front diffuser shouldn't have all those reflections, the sky isn't that blue, thats what gives it up as the bonnet has a "blue-ish" tone to it, also don't take my critic and make it personal or something, i'm just giving you the knowledge that i know and learned, other than that you made a really cool design, keep it up
