Thats pretty much what I do, based on a photo. I do sometimes go to a dealership near my house"they let me sketch the models they have" but mostly just from photos. I'm not that creative I've always just been able to draw what I see.
Hey that would be great, I'm actually just South of Olympia, little town of Rochester. If you are ever going to go in my general direction let me know. I don't know too many people around here and am always looking for a small group. Let me know. My email is [email protected]
