So, this first picture is my quick-and-easy one, that I finished without benefit from that lesson (as is obvious from the inaccurate, made-up shadow!). Oh well.
The cat is from a small collection I have on a table in my living room; my mom gave me one, other people have brought me some from their travels, and I have picked up a couple as well, here and there. I currently have them displayed all sitting in a circle around one of those collectible pill boxes made in the shape of a birdbath, which seemed like a natural place for a bunch of kitties to congregate. But for this painting I had another idea--Mom also gave me this pill box with the Eiffel Tower on top, and--shades of Godzilla and the Empire State--they just seemed to go together!
So, I learned the shadow/reflected light lesson later, and you will see the results soon. The backwards leaning of the Eiffel Tower was a simple error in perspective combined with slanted paper, but it serendipitously worked--doesn't it look like the tower is rearing backwards with alarm from the advent of the GIANT CAT?
