I met a dog, we played Frisbee and I did a drawing of him.
I like drawing people in motion and animals because it requires a type of observation that relies partially on memory coupled with a sort of preemptive composition. I watch for a little while to see if there is a type of pose that gets repeated. I try to remember which aspect of the subject falls into consistency with that context and render it. Life drawing is something that comic book artists should be doing whenever they can.
