These are my contributions to Inktober/Botober from 2013.  I had just completed a freelance gig and had time to participate.  I thought I would "kill two birds with one stone" and do my ink drawing first thing in the morning - no more than 15-20 minutes on a sketch concept - then jump over to Maya for 2-3 hours of quick box modeling.  This was also the time when I was able to fully test out the Keyshot 3D rendering software, and it was incredibly fun to crank out these concepts in a few hours each day.
