A few years ago I designed my own personalized sticker Of my car FOR my car, I went with a Rat Fink design featuring my Artist Avatar Character but for this one I left out my characters and went with a sharp edged stylized take of just the car itself to be a more universally appealing design over on my Redbubble shop.
