I decided to use an extra Face Off Hulk since in in the same boat as most of you guys and cant find the Walmart Avengers MLs. Looking at all of the Hulks out there he looked the most like Ruffalo. Its a straight up repaint. Used a black primer, coated 4 different greens over it. Did a wash and drybrushing. Repainted the head and even added the grayish temples on the sides of his hair like he had in the movie. The paints are a few different browns and tans.
