3D/2D Concepts 

When designing my characters I find it easier to paint on a 3d base to visualize the concept clearer. The big challenge for me these past few weeks has been trying to accurately create a robust 3d muscular male to start designing from. In Zbrush I started with a basic sphere and started to pull out the shape of a human chest. By pushing and pulling out the forms of the muscles, using plenty of reference along side sculpting. Zbrushes dynamesh feature really allowed me to pull out the limbs with ease without any topological issues because of its amazing algorithm. From there I spent a long time refining each and individual muscle. He turned out to be a very muscular fella but I don't mind that he has a slightly exaggerated structure as it fits his brutish profile. Here is the progress during the entire sculpting progress.

Initial blockout

Added more dynamesh resolution and refined more muscle/

Very happy how this was going at this point. Although the arms looked strangely long!

I believe this point was my breakthrough once I properly punched out the chest. 

  

Here is where I finally decided to stop and turn back to the designing stage. Otherwise It would of never stopped! Ignore the dinky little arms for now! xD Now its time to start thinking about him as reckless brute...
