The tools Used to create the shadow itself was that I took the knight image and selected only the knight then masked the rest. And took the paint brush in black and brushed over the knight and turned the opacity down.I used a blur for the knight so that he would blend better into the environment.The connection to the feet with shadow was used with the paint brush in black on low opacity. The displacement of the shadow was done with the shew and warp tool.
