Masked the church from the rest of the image. Flipped horizontal. Cloned the corner that was covered by another building so I had the whole front. Added some moss and vines using pen and grunge brush. Broke out the front window using the burn tool.
step 2 of 5
Masked out the sky, street, people and kiosk. Copied twice and flipped to make a long skinny section. Cloned to fill in some of the gaps, and to make the rock wall from top of ledge. Burn to give the wall some depth where broken down. Pen and grunge brush for moss and vines again.
step 3 of 5
Imported river, transformed and warped it so it fit the path I wanted. Masked out edges that I didn't need. Also cloned to cover missed corners and to add some rocks in the middle.
Masked out tree, changed hue/saturation to make it fit in with picture color. Flipped horizontal and fit into window masking out unneeded sections. Copied, flipped, shrunk and placed at bottom of church. Added a gradient for the sky. Blurred sharp edges.
