Mis en scene

This image is a medium - close up, so we're able to see his facial expression, costume and prop. The mis en scene shows the character is facing towards and looking directly at teh camera, with the gun pointing straight towards it; this puts the audience in an uncomfortable position.
The gun in his hand isn't in that much focus, the gun being out of focus causes us to concentrate on his face and his expression more. The highkey lighting in the image implies that he is the good guy, his costume also gives off the same impression, and shows that he has some sort of authority; on the other hand the fact that his top button is undone, suggests that he's a good person that's been caught up in some sort of situation.
