Looking at these makes me want to stop modeling for a moment, pick up a pencil and paper, and start drawing again.
3-D modeling is different from drawing. There are a lot more technical aspects to it, and a lot more headaches. Drawing is simple in comparison imo. Don't get me wrong though, its fun to do, but so is drawing.
Fun fact of the day: When I am in need of working hard, I have a page of your art up to look at to make me want to continue to push forward. /o/
