To teach myself Zbrush I did a tutorial by Niko Naydenov, based on a concept by Bu Zhou. The above model was the result.
After completing the first Zbrush tutorial, Josh Singh and I made new concepts of a demon brute. The below left is Josh's design. The below right was my concept. I ended up using Josh's concept to make the above 3d model in Zbrush.
