Erasure out of Charcoal Ground Assignment

In this assignment (in class) we were to draw a still life composition.
After covering good paper in black charcoal we were work out the
lights (whites) of the composition and using black, white, and sienna
conte to show depth, contrast, and value.

This is my still life in class. I used the sienna to capture the boldness of the lamp.
I didnt want to leave the focus/weight on the right side of the paper so i added more
on the left in the umbrella handle. The class suggested that i show more highlight in
the lamp instead of completely filling it with conte. Over all i like the composition
and how it leads off the page in all directions.
