Fly like an eagle

Working on a study for the eagle and goat piece. I'm still not sure what medium the final's going to be, so I'm just studying forms and composition, and practicing rendering with a dry sketch. The patron didn't specify a medium, just "whatever you think would look the most epic," so I'm thinking a black and white piece might work best, maybe ultimately in charcoal to give it more contrast. I have more experience with graphite and I think it's easier and neater to work with, but a big charcoal drawing could be a good learning experience.
