The original concept was made by Anthony P for Tom Clancy’s Endwar. Then it was recreated by Steve Warner in a Zbrush 4 tutorial. My project started as just a quick study to recreate some part then I decided to finish it up and try out some color variation and implement some new zbrush features into my workflow.
