See the official Valve "Meet the Medic" video. The (live) Spy head is in Medic's fridge. Also, look for the "Meet the Medic Outtakes" on Valve's Team Fortress 2 blog and YouTube channel, that's the previous version that got scrapped, but has the scene where RED Medic beheads the BLU Spy.
I like the Spy's expression. Like "Oh please, not again. We've already had this in Meet the Medic..."
I'm always amazed by the quality of your pictures. Maybe you could give them a special touch if you manage to remove the slight corners of round shapes, like those on the Spy's head, for example. Just a suggestion; I'm doing it on some screens myself and it looks very neat
