I used one of my old travel photos as reference for this project. I realize I still cannot imagine or invent where shadows should fall he he. One unexpected thing in this exercise, though, I put a thin layer of Prussian Blue on the people and while still wet, put some Pyrrol Red and let them mix together, but still with the individual colors visible. They made the illusion of shadows on the people which I am liking (even if the color placement is wrong in some of the people) and will probably use again in the future. These two colors are also what I used for the dark shadows in this piece.
