I love these off-the-wall, cleanly-illustrated designs. There's a great balance and contrast between both hot and cool colors and the subjects themselves, of creatures and machine. As for the technical aspects, there's great linework, near-perfect anatomy, subtle dithering, and fantastic lighting. The entire composition of the image works out well as a t-shirt, and wears well with the curves of the body (even for guys too, I bet!)

I can't wait to get this one in the mail. :)
