This one was tricky, I considered tilting the camera as I took the picture so to accentuate the perspective but that would be cheating. As no one but myself is currently checking this blog I would essentially be cheating myself. The feet look web-like but this is not a foot "sketch study". Though, I do plan on devoting some time in the future for that. The hardest part of this was the shading in conjunction with the muscle formation. The source image must have been taken with focused lighting as opposed to flood. But to make it so the muscles and shaded area were both clearly defined yet discernible from each other was tricky.
