Drawing of the Day

This is the beginning of a drawing that I'm copying from Through the Lens: National Geographic's Greatest Photographs. The photograph by A.W. Cutler was taken in 1929 in England. There are several children playing in tide pools but I've decided to focus on just these two boys which I think makes a better composition for a drawing. Tomorrow I'll start putting in value. This way I don't have to spend all night on it and you can see a bit of the process. For anyone who cares.
