I find that some of the drawings, the successful drawings, tend to draw them selves once i've outlined its principle. Others, though, capture too much of my ego and get clogged up.
Still, though, I force the art, hoping it will turn out some kind of well-rounded character if I just give it more time, more color, more graphite. In each of them, though, there's something that I missed, and something that I'm meant to learn. It's still tiring, though, when I'm pushing the thing but it remains lifeless.
The most recent one I'm working on is definitely breathing! I just wish I had more time to work on it. I just moved, and am working out my employment situation (with some success!!). Soon I'll be able to get back to a regular drafting schedule.
