How to draw forest ruins with charcoal.

When I started this drawing I had no idea what I was going to do eventually come to the idea of light coming through the tree and the foreground being darker than the background.

I wanted to play around with the light.

I wanted to see if I could understand how light follows the form of whatever objected it follows. You see light itself is formless it has no form or shape to it instead it takes on the shape and form of any object it interacts with.
