It took about 6 hours of working to get on this result. It was sculpted using Multires and Dyntopo, the base colors painted with vertex colors and the rest of the texturing was done in the materials, rendered in Cycles using Pro-Lighting Skies. Based on the on concept art of Tim Von Rueden.
I'm really glad you liked Tim! You did an awesome concept on this guy. ;)
Just stumbled upon this again. Looks so great!
