Here is the creature I made for the Gnomon master class entitled 'Creature Head Texture Look Development'. I made some style variations in Photoshop starting with a simple layered comp rendered from Maya. About 30-40 minutes each. Very fun to do! I create these at 4096x4096 so that I can project the image onto my model in Bodypaint as a solid startpoint for final texturing. Click on the image for a high-res version.
