another awesome piece
Great work again.
I'm digging the skull. This may just be nitpicking on my part, but it's so close to being anatomically correct. The only things I can spot right now are that it lacks the sutures and the cheek closest to us should be a little more pronounced.
Aside from that, the background blends into the foreground a little too much and it's hard to tell where what ends and when what begins, etc etc. Also it looks like it's a skull attached to a fully fleshed (yet skinny) human body. I'd suggest making the clothes much more saggy and wrinkled, and really emphasize some highlights where the bones would meet the cloth.
I'm a little out of it at the moment, so if any of it doesn't make sense or you're just not looking for critiques, let me know.
Regardless, great work!
