Love it! What better way to start of the Halloween season then with a little finger-related cannibalism? I have seen several "finger pictures" before, but none of them comes close to the creativity displayed here. Each of the fingers clearly has his own character and personality - a lot to say about simple picture, but still very true. Capturing so much with so little is what truly makes a great photograph.
My favorite is definately the zombie finger! He is positioned so perfectly, and is definately the most believable character (and just so cute!).
The only thing that's off about this photo is the sliver of green nail polish on the vampire's head, which keeps drawing my eye away from the faces. Everything else is wonderful! Excellent use of materials (and fingers)!
