The end of the cigarette doesn’t make sense, it almost blends with the background. The smoke is also clearly wrong and a bigger indicative of this being AI generated.

This font in particular is extremely common in AI generated images, it looks off because it is not a proper font with defined characters But rather generated, that’s why you have two sets of “G” instead of one, you can probably find other inconsistencies there if analized thoroughly.

Also, the outline is inconsistent and looks jagged at times, which doesn’t make sense. And the door frame stops existing near the hair and the hand.
