The Ascot Gavotte

I drew this when I went down to Iowa the past four days...I didn't have any other reference except for the Audrey Hepburn biography, so...yeah.

I tried to do three different types of shading: Just build up tones, completely smudge with a tissue paper, and cross-hatch. Of course, this rubbed against the other pages in my sketchbook and the cross-hatching was ruined :/

I was stupid and forgot my drawing supplies, so I just used a regular pencil.

Any critique is really, really welcome :)
