Gerald Cassidy - Motivating me to improve

This is my rendition of a charcoal sketch by southwestern artist, Gerald Cassidy.  I was blown away by his handling of the darks and lights and copied his work as a way to improve my own and to get me to think more in shades as opposed to just lines.  I don't know much about Gerald but, I plan to do more research on him.  I will see if I can find any on-line links for his work or his biography and will post it on a future blog post.
