These are two 10-minute studies above, and a 20-minute one below. The top two are done with hard compressed charcoal on 18 x 24" sheets of Canson Recycled Sketch paper, and the lower one is the same material on a 24 x 36" sheet of Durotone paper.

Did I mention - it's not too late to sign up for TSA's spring term classes? My perspective class starts this Friday aft, and there is a very interesting, more experimental life drawing class, Explorations in Figure Drawing starting this Thursday morning. It's co-taught by the very excellent Gillian Iles and Paul Turner.
Plus there's still room in my more straight-ahead life classes, which are only 1 week into the 10-week term.
