Life Drawing: Anatomy Study - Legs and Feet

For the night, I worked on legs and feet, while working with perspective as well. This one was extremely challenging, as the lower half of the leg was partially masked by the blanket the model was sitting on. With it masked, when drawing that part of the leg, it was almost an optical illusion trying to understand that the leg didn't really go down, but out and back. Regardless, I was able to finally capture the shape, and add the muscles.
