Creating a stencil using Photoshop

To start off the process i chose an image of an urban environment and a piece of art from the internet which i would then merge together. The image of the artwork was edited to look like a stencil, for this i adjusted the threshold level and used the pallet knife to manipulate the stroke size. Using the move tool, i inserted the stencil onto my background. To add the effect of the train going in front of the artwork, i made a copy of the train and inserted it into a new layer. I used the transform tools and the multiply tool on the artwork's layer to position it and help it blend into the background.
