If you are looking for "what's odd with this picture," I can name a few more. I wonder who waters their plants. They are awfully tall for a normal humans, even if they are standing on stairs. You're right Element. The two on the outside are dressed like each other as are the two on the inside. I'm not sure about the twins thing but they certainly resemble one another... all four of them to their chosen twin. There is a guy standing between the two girls in the shadows. He is defintely shorter than the rest of them. The hand on the girl who is pointing is wearing, what appears to be a bandaide on her finger. There is what looks like a gun on a chips bag above all of them.
