using a green screen fail + guitar neck snapped. [Here comes fate video]

This was a 1st attempt at a green screen shot at home for a scene where I walk on top of a car to play the guitar on the roof. The car was a slot car so I was shrinking myself down. The scene was set inside my friends living room. Didn't all go to plan and I fell and snapped the neck on my washburn guitar.
I eventually set everything back up again and redid the shot.
