Hey, just starting this one after composition 1.1. I think this is the next logical step.
Here's my first one. I think it is a medium key, right?
It got me curious about how to communicate the different colors of the skin in black and white. My nose was a little red at the time, and I tried to make it a little more darker to suggest that. Same with the cheeks.
As I said to another who used a similar approach...I would recommend taking a look at sargent's and velasquez paintings to study the brush stroke directions that define structure, including the head and the neck. The light on the ears should describe the light direction and the planes as well. The light on the ears suggest the light is all hitting the same planar direction at the moment when the ears have a variety of top and side and bottom planes. Great job on massing in the shapes of the light and shadow overall.
