Thank you Tony. Thank you Douglas.
Two new tools that made this composite easier to put together (besides other tools) were the "Rotation Tool" and the "Harmonize Tool". All it took afterwards was some minor retouching to the results. Before it was a pain trying to find the right photo, with the right pose, the right perspective and light direction.
Every single element, person and animal in this composite have been rotated and harmonized in PS, including the building on the right side I added to the image to match the scene.
