Sorry for the shitty pic--it really doesn't do it justice. This was the last part of that lower-leg Godzilla sleeve (sock? Pantaloon?). That's on the back of my leg, with Godzilla on the left side and King Ghidorah on the right. I'll have some good pictures of the whole thing when I go back for touch-ups.
Edit: Oh, it's from this picture, but he kinda had to change it a bit because of King Ghidorah's ridiculous fucking wingspan.
