I am very, vey impressed by this. It's especially the expresstion that caught my attention, the way they looks so different while it's clear that they're the same thing. I like the way one's eyes (Face?) is hidden, but there's a mouth to show expression, and the other one looks at me in a curious way. The way you've painted it, the chalk-like manner, and the colours you're used, together with the rather simple background who's still very good made creates a perfect mood. I am really not sure if he's nice or not, and I love it ^^ Are the two heads the same, or is it like ... nice-and-cruel-half?
