I was playing with the Image Composite Editor earlier throwing together a panorama of my back yard when I accidentally ran across ... some un-composited images of my back yard from nearly two years ago.
There's no singular landscaping or construction event between these shots so they're not really "before" and "after" but they are definitely separated by two years of work and growth.
...and deck furniture.
Looks like you filled in that gaping portal to the underworld in the last two years, too. Totally improves the yard.
I filled that part of the yard entirely with 28mm-equivalent wide-angle lens.
