I think this music if fitting for the image:
This is Fantastic! Fucking winner!
Wow, I haven't seen something this awesome in a long time. Fucking good work.
What would I do? Hmmmm.... awesome stuff, you habe yourself a winner!
RED spy should be angel, since BLU spy is about to attack RED engineer and thus RED spy wants to save RED engies life.
BLU spy should be devil because spys job it to kill him, as engie is opposite side.
Though that is my opinion, rest is done really good.
Heh. This is pretty well done.
