Nice to see both submissions on the same page and compare the differences! The right one definately looks better than the left. He doesn't just look better defined but also bigger, but at the same time it's like two different styles in the different pictures. One thing I thought was pretty cool with the 09 version were the blue glasses, they really glow. On the right one they do look more realistic, but the whole picture is also dark, I feel it would be nice with some color added!
The black line separating the lips on the right one looks a bit odd when there aren't any real outlines elsewhere, otherwise it looks great, the facial features look realistic and professional, as does the shirt. The afro looks.. unreal, but then again, don't all afros? :) Much better shading on the hair in the new one! Keep it going!
