Ok, these aren't really coming in order, but I thought I'd post my favorite recent sketch next.
This is a morning sketch of my office after a night on the sofa. Still just getting back into the groove of sketching with a rollerball in a sketchbook. It's been so long.
Sketch is done with a Pilot Precise rollerball in a hand•book 5.5 inch square sketchbook (from Dick Blick)
