In an effort to up my rate of sketching and drawing I've been doing some sketches from photo refs, working from the computer monitor, and here's one of them. Not a great picture I have to say, it looks a little distorted, but you get the idea!
A4 sketchbook, black kuretake sketching pen and grey tombow brush pen.
These are fun to do, and I was pleased with this one, from a fairly unpromising snapshot. Sketching in pen also means that I don't go back and fiddle (too much...)
