A concept designed by audi, not me. Unfortunatly. I've spent quite a while doing this part do far, as I think that if I spend more time on my drawings, I can make them look a lot better.
It's a Le Mans Quattro concept. Here's the ref:

I'm going to do this as a kinda shading tutorial, as some of you seem to want to improve in that area. Don't move it to the tutorial section though as it's only annotating my sketch, and I want to show this off as one of my pieces.
OK, here's the pic and below is a tutorial of the shading.
EDIT: hang on if you see this, I pressed enter by mistake.
