Here's the character that I created a few weeks back that I used Photoshop to create reflections in the gas mask lenses.
A close up of the lenses. Definitely not perfect. I haven't figured out a way to get the 3D mapping to look right.
This illustration is part of a character series for my "claylist" entry to ArtPrize 2015. I'm doing this to force myself to learn new techniques. Any input is helpful.
