I've been working on this for almost a month now, between getting addicted in minecraft and a few road trips. I started with a simple idea, I was going to model the upper chest and a part of the shoulder just to get a portrait done, but then I began to do the lower parts to fill the frame and when I saw I was already at the wait, so I just kept on going. I know it would be better if I modeled each part separately but I didn't really begin this with a plan. There is still a lot of tunning to do on the details and some things to fix, but I'll texture it first so I can nail those spots.
