Preliminary Sketches for Paris Drawings

I had done some drawings from my sister Diane's photographs of Paris. I gave the finished drawings to her as a gift. She loves Paris and visits each year.  I wanted her to have some scenes to keep. I've never shared these preliminary sketches. They have a slightly different feel than the originals. The medium is charcoal on paper. I was just trying to work out the compositions. 

The bottom finished drawing was called TREASURE SEEKERS because my sister loves crows, and both crows AND Diane are known to be treasure hunters. They both search for treasures wherever they go. I was working out how I would have her meet a crow and exchange treasures.
