Ouroboros. Really fun to say. A sweet, dragon-related, symbol for infinity.
Used 'pattern along path' style for scales (very taxing on my computer's memory when it came time to scale and move it). I've been looking at some great vector illustration and trying to break down how the artists produce the shapes and strokes they use in their work. I like the way the head turned out, even if it kind of looks weird in relation to the rest of the body.
