I like your use of lighting. You are walking that fine line between light and dark and the red light lends itself to the "taboo" of severing the limb. The manic happiness makes the act believable as well as enjoyable. Thanks for sharing.
not that my critique counts the lighting really for me just lures your eyes right to the fake leg and your mind takes that moment to unscramble things and go "ok" -chuckles- I'd love to see more from this shoot.
