It's a weird distored ninja turtle head. It didn't intend for it to be a ninja turtle head at first. It was just a quick sketch with a weird expression. Then I thought the shape was similar to that of a ninja turtle head, so I added the mask, shell and spots. This is the same one as in my scraps section.
It was original done on printer paper and pencil. I then scanned it in and added the colors in photoshop through the use of the brush tool.
