Okay, so maybe not blindfolded - but certainly without the aid of corrective lenses. The older I've gotten the more I need glasses while sketching. Without them what's ending up on the paper in my lap is pretty fuzzy. Still, I persisted with this sketch and I actually think it helped focus me more on overall shapes and to ignore tertiary details. This was a 10-15 minute sketch to practice proportions, shapes and shadow mapping. The subjects are the actors Robert Young and Jane Wyatt from a promotional still for the old TV show "Father Knows Best". I'd grade this doodle of mine a "C" for effort. The likenesses are fair and the shapes almost accurate. Certainly, after the fact, I can see many missteps.But what do you think? As alway, much more study is needed :-) Blue prismacolor pencil on white copy paper, approximately 4 inches x 4 inches
