In the first one you have good use of leading lines into the couple but they're somewhat lost in space and the overpowering colors of the background. Vertical distortions on buildings are difficult enough but any movement off center will cause unequal distortion. A lot of corrections can be made in PS click on Filters > Lens Correction > Manual > scroll down toward the bottom, or in LR vertical and horizontal sliders at the bottom, the develop pane. I use both.
I actually prefer the 2nd image but the off skew window is killing it. As vertical and horizontal adjustments are global and the couple is already pretty much vertical. In PS try going to Edit>Puppet . Warp images, shapes, and paths in Adobe Photoshop set anchor pins around the window then slowly drag each to warp the window.
