Yoda
Here is another rejected design that I liked. It was for teachers at a local school to wear on the first day. They went with a simpler Yoda head, but I really like the first drawing.
Grinch
I started this project a few days ago. The customer is doing a holiday fitness challenge and wanted to incorporate the Grinch or another Dr. Seuss character. I found a reference pic from How the Grinch Stole Christmas and instantly thought of a squat pose. I came up with the slogan from one of the lines in the cartoon. Some personally rejected lines were "Pants feeling two sizes too small?!?" and "Still reaching for that last can of Who Hash?"
