POST #12: Sketch Number Ten

I intend to finish adding values and a background to this sketch.  Once it is complete I will add a finished image to this post.  I also hope to begin photographing all new sketches in proper lighting with a more efficient area for shooting photographs, and I plan to take new photos of each of the earlier sketches and update older posts.

Here is the unfinished sketch as it is now.

Here is the sketch in several different phases, beginning with the 17-minute mark.

Here are a couple details of the sketch as it is now.

Here is a shot of the setup I am currently working with.

UPDATE

Below is the finished drawing, followed by some process photos and details.
