This was done from a googled photograph (gasp shock!) but it was enjoyable none the less! I was looking at a few of my favourite painters for inspiration on how to simplify areas and not use the pic slavishly. The biggest difficulties lies in the drawing, since its hard to get your head around how it works in 3d space. Easier if you're in front of it, so you can go round, "understand" how the car is built.
