multiple exposure feature

I just started using the "multiple exposure" feature in my camera (so much fun) and this is what I came up with. No photoshop except for color/sharpness. Multiple exposures were done in-camera. For the first picture, I focused on Sam for one of the exposures and focused on what was behind him for the second. For the second picture, I had to turn the camera completely so that the 2nd exposure would be exactly the opposite as the 1st.
