Here's the raw scan of the line art post.
I won't repeat the full image description here; I'll just add that a cyan sketch is visible under the pencil lines, including several attempts at the back foot. The background is a dull light gray, with the paper texture visible. It was white paper; the scan was just really dim for some reason. (Some of it is possibly smudged pencil lead. A couple splotches are visible on the right.)
