So I started out with a shapeless blob, and a ZSpheres rig. After some sculpting and a great deal of attention to details, I got Brock's upper torso sculpted. His lower torso and legs I re-built three times until I got it right. For his shoes, I used one of my dad's loafers as a reference. And then I just reused the hands I made for my first model on Brock.
I tried to pose him using the armature tools, but he got all bunchy and crumpled looking, so I decided to come back and work on him after I learned the new methods of retopologizing.
It took me about 4-5 days to build Brock Samson after having worked with ZBrush for four weeks. Even though I'm not very skilled, yet, I'm quite pleased with how Brock turned out.
