Two points
Although originally I was looking for triangular shapes and though the statue of Eros, in Piccadilly, would make an interesting choice, as I was taking the photo, a pigeon flew past. The image now had two triangular shapes! I also thought it would be fun to edit the photo so that Eros too appears to be flying. Eros and the pigeon can also be considered two points. The larger figure of Eros, looking down, is balanced with he pigeon flying upwards.
