Then I had to crop off the excess at the right...and correct the bulge in the wall where the two picture elements were merged. I used the Liquify tool in Photoshop to fix that and the slight bulge below, plus a tiny one on the left - not perfect - but all in all looking better on the next image. (In retrospect I cropped too much off the right before I moved that area over, so I had to add some detail back in a later version!)
