This is an original character I've been working on for a while. He was inspired by the Tortle race from Dungeons and Dragons.
I will likely revisit him at a later date, since I want to update his design to have armor, as well as give him unique accessories/weapons.
Base mesh was modeled in 3ds max, and then I moved his body to zbrush for sculpting, and textured everything in substance painter. Renders done in Marmoset Toolbag 3
