You got it. The key to almost all successful editing is not to overdo things, but to reduce the problems subtly to just below what I call the "distraction threshold". This is also especially true with noise reduction (though clearly that's not a factor with this image).

Oops, I think I accidentally hit the "Edit" button on John's post instead of "Reply"
John had said something like "I see you corrected most but not all the perspective, which made the change not noticeable".
Sorry about that, John. I'll try to be more careful. The awesome power of Moderation is a dangerous thing (for me to wield).
