Ben as Murk Upchuck. Transparent background.

Negative Murk Upchuck. His color scheme is inverted for the areas covered in green with dark spots. The skin on his face and torso is a paler shade.

PS. Which art style (OS, AF/UA, OV, HU) is the most challenging for you to work with? Somehow I suspect the latter.
