Those are some impressive comparisons.
That said, I noticed:
.
https://imgsli.com/MTU1MDkAt the castles at the back on the bottom of the screen, the cutout transparency is a bit off and there are some "ghosts" left. Adding to that, as a suggestion, it looks like those castles are supposed to be blurred, like a camera effect;
.
https://imgsli.com/MTU1MTAJust a suggestion again, those castles on the left side could use some touch by hand to blend more with the background. Maybe a little color change/or remove the whiteness/or a bit of blur;
.
https://imgsli.com/MTU0MzMThe lamp post on the left became too thin, and that lamp has the bottom part removed; The background city could use some camera blur (looks like they were aiming for that look); The original font looks like has some transparency;
.
https://imgsli.com/MTU0NDIThe color on the railing/gate is much darker than the original, but maybe is for the better. Still, it could be a bit brightened;
. Some or most of the screens are a bit misplaced if comparing to the original. Like they are slightly moved, so some npcs are not where they should be, some sitting in chairs that are a bit off/etc - but it might only be noticeable if comparing side by side.
. As was already mentioned, sometimes the clouds are better using waifu, but sometimes are better with AI (maybe use a mix?).
No need to follow everything I said, it's just me nitpicking it's already awesome as it is.
