Hey there again, I also wrote a reply to your comment in the other thread. You know, at least you've got the right idea about it. It's all about the brain telling the hands what to do. It might sound silly, but I've had so many people tell me I've got a "great hand" or something along those lines. They thought that the skill lies in my hand, not in my brain. Which isn't true of course. I can even draw relatively well with my non dominant hand, even though I can't control it that well.
So, you say you can't draw. But have you actually seriously tried to learn? Did you look up techniques, study anatomy (or you subject of choice) and spent hours practicing? I find that a lot of people think they can't draw, but they've never really tried.
