Adobe Premiere. Additional sound effects. Foley Sounds.

I used Garage Band to record the additional sounds.

Tumble Weed - Rustle a Shopping Bag (Sainsbury's)

Cage Shaking - Nails on Metal

Paper - Waving A4 in the air

Saloon Door - Door - 1 - Open (Taken from www.soundjay.com) 

As a last minute decision I have added shadows to my scenes.
This was done by adding a 'Shape Layer' and using an effect called 'Gaussian blur'.

I imagined where the sun would be when adding the shadows.

I feel It was done correctly, especially when the sheriff is talking to the cutlery. The characters are standing opposite each other, so the shadows appear on opposite sides.
