modeled drawings

I am redoing a lot of the exercises I thought I did properly from the Kimon Nicolaides book "The Natural Way to Draw" but realized that I didn't. lol Here are 25, 50, and 50 minute studies in watercolor respectively. Boy I am SOOO happy I went back and redid them with a proper model. I've learned so much. The lithograph and ink studies were really difficult for me, but I feel like the watercolor studies are looking better. That may or may not be a good thing though. lol
