Kilowog
I had a build a Kilowog head from the Sinestro Corps Superman that just came out. Thought the head would fit on Thanos and that's how this started out. Used green stuff to sculpt the abbs and the giant lantern ring.
Hand Painted the symbol on. The head originally had a rubbery look to it and I decided I hated it. So I repainted the head and carefully drew on his eyes.
