Nope. It doesn't exist period. It's entirely freehand drawn-digital.

Not to brag, but I accidentally selected the ORIGINAL PHOTO I referenced this from, and handed it in to the teacher, and he had no clue it was the wrong photo until the last minute, and only didn't give me an F on account when he saw the ACTUAL piece he understood why I would make such a dumb obvious mistake. Adobe Illustrator.
