Here is a concept mini van, both in the early development sketch stage and the rendered drawing.  However, like many of my drawings, this one has evolved even further since the digitalization of the rendering.  The original remains tacked to my wall above my drafting table but now sports a blue background.  Evidence that a piece never stops evolving until it is framed. 

Of course, the real question is: Would you buy a vehicle that doesn't have turn signals or windshield wipers?
