Pencil and paper, done with a mirror, so the features are actually inverted...
Took me some ten to twelve hours all in all.

Closely following the instructions for figure drawing from Tony Ryder's fantastic book I can say that this drawing sort of was a milestone for me and I will do more pencil/paper drawings, but preferrably not with me as a model again...

Bit of postwork was done in Painter IX.5 to clean the scanned image up.
