Personally I had a difficult time with Object and Shadow because I could not get the shadow as crisp and hard as I wanted, but I made due with what I had. The first two pictures are of the tools that I work with every day for Stained Glass. So because I work with them every day I have a personal connection with the tools. The third is of the rear of my truck, I wasn't planning on taking this picture, but I walked by it and took the opportunity. The fourth photo includes irony with a no littering sign with a piece of garbage in front of it with the shadow of it behind it.
