I borrowed Drawing Lab from the library and have been enjoying the exercises. Here are the results of about 5 minutes with a chiseled marker, a stack of index cards held in my hand, and a restless dog. She started off staring at the back door and giving me meaningful looks over her shoulder, so I let her outside. She lay down for a minute, but then my model ducked behind the barbecue grill. I think she knew she was being watched. Nice little warm-up though. I'm going to play around with the blind contour drawing challenges next.
