I will be sculpting out Don Cheadle as War Machine.
Below is the begnning base mesh, and the progress so far on the sculpt. The base was made in Maya. I could have sculpted this from a minimal base, but I wanted to revisit some good old poly modeling to allow for some extra control in certain areas.
I will most likely try some of the hard surface brushes for the armor, at least as a starting point for retopology.
