It's very difficult to see the differences as displayed, so I've had to save and open them in PS to give you the critique you're looking for. Before that, however, I'll say that I probably wouldn't have noticed anything in the second photo just from seeing it here. And only because you've asked I'm going to dive
deep into these -
far more than I would during simple observation.
OK, Photo 1 - Side by Side:

This one was/is problematic in a couple ways. The original image had some skewing issues (plural) and you can only fix one, and I believe you corrected it properly. The tower has a definitely left lean (pink lines), and that's the most important and obvious aspect to correct. Your correction is more than sufficient and is a big improvement over the original. With that said, I just want to show you just how ridiculous it can get.
While the tower appears straight, the lack of alignment of the windows suggest that it isn't - even thought it is. Why? You weren't standing dead center but slightly to the left of center (yes, I obsess about this when shooting symmetry, but only because I hate it when I notice that it's not perfect when I bring it onto the computer). The yellow line should run straight down the center, which would also correct the sky triangles, making them equivalent (the left triangle was drawn from the photo and then mirrored and brought to the right side for comparison). As you can see, the corrected photo is
much better, but does not have perfect symmetry (which it
doesn't have to have - I'm just being REALLY picky).
Can you fix it?

Thank you Free Transform. But is it "fixed"? Hell no!! It's even more broken!! Now I've skewed the lines in the stones, and while the lower window is centered it's now skewed. I
could fix that by masking out the transformed tower and painting in the original stone work.... Aaaaahhhhhhh!!!!!!
My point is, your original correction is perfectly fine. The rest is just obsessing, and were this for the front of a park brochure or something I would
probably recommend a reshoot with all the obsessive stuff fixed (though the printer would probably cut it off-center - LOL), but if I were asked to judge this in a contest or something I would likely never even mention it in the critique, assuming I even saw it in the first place.
And just to be complete, here's a side-by-side of the second photo. Yes, it had a left-lean, but not much at all and is hardly noticeable as is, but the correction is perfect.

Aren't you glad you asked?
