This client requested a "Metal" sleeve. We both drew inspirations from some metal band art that he brought in, but this entire piece was drawn from scratch. We have included: A demonic goat skull, A decrepit Pentagram covered with thorns, some crazy morphing bird shapes, and a glowing eyeball nestled inside of a gnarled, bandaged hand. Yup, gonna be lotsa' fun!! Note* The Cowboys from Hell logo was pre-existing and not done by me. We are going to incorporate this piece into the grand scheme.
