Thanks for the nice words! As for that picture, it started out this way (see first photo). In Lightroom room I applied a lot of alterations:
Vertical: -70
Horizontal: -7
Rotate: -0.9
Scale: max left (50)
and cropped left and right to retain maximum vertical image.

And since you asked about that one, this is what #4925 looked like at first (see second photo). It was fixed this way:
Vertical: -75
Horizontal: +54
Rotate: -6.8
Scale: 65 (almost all the way left)
and crop to remove the distorted right edge and cupola. (Note the white triangle in the upper left corner--there was no image there to be seen with the vertical correction.)

You will note the use of the LR "Scale" slider. I have found that when major vertical corrections are needed, the original image space is not large enough to contain all the image data and it gets truncated. I use "Scale" to enlarge the image space enough to retain all the data, and then crop out the extra white space around it. Extreme vertical fixes also make the image appear too skinny, so I sometimes use a little negative "Aspect" (slider to left) to fatten it out. Didn't think it necessary this time. These are tricks I have recently learned to create images that represent what I saw (or think I did).
