Just one--this week's drawing from class--but I think this is definitely the most detailed and complete one yet. With 5 minute breaks every twenty (for the models), this was done over the course of about 5 hours. Vine charcoal on German Etch heavy rag paper--this stuff is 75% cotton and a dream to work on! Great texture and color. I'll have to get more--I just wish it wasn't almost $5 a sheet. The angled crop was interesting to work with.
