I used a stuff animal, a fishbowl, and mirrors for the center subject matter in each photo. All my photos are horizontal. The distance of the animal and fishbowl are more close up then the far away distance of the mirrors. Most of the center pieces are put together like a puzzle. Theirs many lines and shape in each photo.. Not to much background in the diptych with the stuffed animal though. They all are unified together. They don't really have a meaning towards each other.
