Here is another sweet concept by Paul Mager. I like how the expression reads even if it isn't an exact replica of the design. This was mostly a study in hands and wrinkles.

Two-Years-Ago Eli would have been sad to hear me say this, but I am pushing more into realism and I like it. Cartoony stuff is my strong suit, but I'd rather be well versed at modeling anything and everything than just nice beautiful appealing characters. I don't think that I'll ever believe that a perfect CG likeness is better than the real actor on screen, but for things that don't exist and need to be photo-real, I am willing to ZBrush to death. (Things like dragons and stuff) I am calling this guy and diving into sculpts that are much more dynamic.
