More sketching while watching TV

It is tough to draw moving objects, and even harder to make it look like a specific person! This is supposed to be Jim Caviezel in "Person of Interest." Not a good likeness, but a good exercise, nevertheless. I love "urban sketching," but my goal for this upcoming year is to work on portraiture. These exercises are for the sole purpose of developing my eye for features.

By the way, how is your 20 minutes going?
