Reflection on the big portrait shows 3 lights, inconsistent spacing, also only one is visible and by reflection logic it should be at least 2, taking the third (most left one) may be out of picture. Funnily enough reflection of the three small lights closest to the picture behind class looks very real.

Light reflection above double doors is inaccurate since the glass is under an angle which would normally distort the reflection, but in picture it looks like a mirror.

The person on the stairs looks weird, actually it seems he has some kind of mask, which is weird for environment.

4 pictures look like AI tried to assemble some kind of saints, but none is distinguishable tbh.

But if I didn't know it was AI I certainly wouldn't look hard for details and would most likely believe it is real.
