I love the cheek shadows and plates of the what I'm guessing is horns (yes, no?) The angles of the chin and jawline are phenomenal as well, and although I can't see it, it appears their chin would rival Bruce Campbell. Careful with the mouth, though, the angles seem to be a tad off, not sure if you meant for that just a bit distracting however, and on the edge of the cheek leading up to the fore mentioned horn, the depth of the picture gets lost. Like, that parts of that ear-like space just seems depthless in a way, especially as it goes up toward the horn. Even so, it's a stunning piece, and the most notable part is the expression, which for such small amount of actual visage, you capture it very menacingly. I think you should try this much more often ^^
