I've been reading up online on various animation and art blogs and information sites recently. It's a great way to keep up with the industry, but I've been finding some great gems in there as well.
Here's one that I'll be thinking about for the weekend. In referring to drawing (especially gesture drawing, which is what most of thumbnailing and storyboarding is), you need to focus on where the weight is. And Sheldon Borenstein, one of the professional posters on my class website, says that "The nose knows". Meaning, draw the head (as a circle or egg shape) and make a straight line down to where the feet or ground plane would be. This is where the weight should be.
I don't want to violate copyright, so I won't post his drawing, but check it out for yourself. Look at a drawing, painting, or even how a real-life person stands, and imagine a straight line down from their nose. Is that where their weight is centered? I bet so! Cool idea! Crazy how the body gives you all these clues, if you just know how to follow them!
