Here's a concept sculpt I did for a client to be printed at 28mm scale. Check them out if you have time www.spider-monkey-games.com/
The model was entirely sculpted in Zbrush using mesh extraction, clipping brushes, polish brushes, custom alphas, and some of the default insert mesh brushes found in Zbrush. It was a fun project to work on and was inspired by many of the awesome concepts found here and elsewhere. I hope to be able to do more stuff like this in the future.
