This summer a grad friend generously gave me an hour's worth of time to do figure drawing, and the sketches reminded me of a similar situation about 30 years ago when a fellow art student did me the same favor. Both sets of sketches are posted here.
The first three sketches were done in the studio at UM, the last three were done along the streets in Urbino. The Italian Tratto Pen works wonderfully on Fabriano F4 paper.
