Rebel Yell colored-Strathmore Toned Gray 80 lb acid free paper, Prismacolor Colored Pencils and metallic water colors. Had watched Hobbit 1 and 2 and that is what made my mind up on the skin color. I liked the idea of the white ork. Not really sure if the scan shows but the copper and the metal or silver was done in metallic watercolors and has a very nice metal look to it. Might have to do this one in a sculpture.

I love this one, very awesome! The designs carved in the skin are cool, it would make a great sculpture.
Thank you. It is on the list. I had fun with this. First time using the toned gray paper.
