Faces are hard, but I'm learning why. Humans are so darn good at face perception. So if a nose is slightly large, or ears are slightly off, everyone can tell it doesn't look right, even if they can't say why.
Conversely, things like hands, feet, shirts, and swords are much easier. People can still tell if they're wrong (e.g. if a hand is too big, or a sword isn't straight), but there's a lot more leeway. After repeatedly practicing faces, it's a relief to discover the body parts I've been neglecting don't require as much practice to get to the same level.
Also, I think I'm starting to like drawing hair. This is a big deal.
I might try drawing from imagination again next week. We'll see. Copying pictures/life is fun and all, especially when it comes out good, but it's not what I want to do. I want to be able to draw whatever, whenever, you know?
I think it's the same desire that causes me to write. I've got worlds in my head, and I want to show them to somebody. I want to show them to you.
