I almost called this one 'Shadow', but then I found this word 'Galanty', which is a kind of Shadow play. What better name, because you should play around with these shadows. Any shape works. Try the shadows on top,on the bottom. Elongate them. Add a little space between shape and shadow. Then decide where the light is coming from, and place the highlight to show it. And remember to have fun! If no such shadowing exists in nature--why you've just created a whole new shadow play!
