The best drawing teacher I had in college taught us very a little about drawing and everything about seeing. Seeing is the key to drawing well. Once you know how to see moving the pencil is just basic mechanics. Anyone can move a pencil. Since my focus has switched from learning how to do art to making my own art I've gotten slack on seeing. I can see how I want things on my page, but I don't always see how things are when I look at them. Today I took some time to look, draw, and look again and erase and draw again in the hopes to get on a training kick. I firmly believe in the necessity of classical training for artists, and a solid grasp of technical skills prior to venturing out into the wilds of creating professionally. It's a controversial view in some circles, but if you can't see you're blind.
