I'm adapting to the new dimensions, but I think I need to either find a different paper for the longer poses or use a different drawing implement. I'm leaning towards compressed charcoal and maybe a white pastel instead of the conte' I have been using. Overall I got some very good poses from this model. (same as Session 6), and I'm very pleased with the 25 min drawing.
Happy New Year! I have decided to upgrade my paper size this year. I was working on 11x17 and I am now working on 18 x 24. The first thing I noticed was that my gesture drawings were a little less restricted which is nice. The second thing I noticed was that there would be a bit of a learning curve with the paper quality and management of time with the larger surface. Enjoy.
