Playing with charcoal, water and color editing - "Silence"

I recently watched a portrait artist use powdered charcoal and water to create a portrait.  I have yet to truly understand the medium but here is my first attempt with it.  11x14 charcoal and water on Bristol paper.  The top image has been modified by the computer to have a blue cast which I felt imbued an added depth of emotion, the bottom is a close-up of the original. 

Graphite self-portrait

Sisters

'Sisters' is a painting I did just for the joy of it.  The little angel on the left is a dear family friend.  Her photo is circa 1940.  Water color on paper, 11x14.
