Ambigrams & Illustration

Working on some fund-raiser graphics for an ex-coworker and musician who was injured in a car accident. He'll recover, but it's a long road ahead. So a bunch of his friends are putting together a fundraiser for him, and I'm working on some graphics for it. This rough sketch is an idea for a feature graphic to be used on tshirts, flyers, etc...and of course, a variation of an ambigram I've done before. And can you find the hidden surprise in the illustration, aside from the ambigram? ;)

What do you guys think?
