FlameRaven - I like that idea. But since I live out in the woods and work alone, it would probably be easier in my situation to go to a mall or someplace public with lots of people and speed-sketch. I've tried speed-sketching from photos, but its not as energizing as doing so from live models.
Thanks for the suggestion.
Mirana - Good idea! I've got some big graphite chunks that would be very handy.
alesoun - Your post reminds me of an exercise I did way (way!) back in college. Our drawing professor had us come to class with a stick at least 2 feet long, at the end of which we attached a sumi-brush. Then he had us do warm-up sketches using india-ink and holding the brushes from the end of the stick. Talk about loosening up!
Last night I slept like a baby: I wore a diaper.
