Some context, expanding on what @Brewstice already mentioned:
Almost all of the animation was taken from 4 non-sequential shots from Benek's previous work "MetroiDance", released Aug 22, 2022.

Shot 1: Pole in 1:17 of MetroiDance
Shot 2: Poses in 1:14
Shot 3: Crotch shot in 1:16
Shot 4: Gun in 1:34
The backgrounds however, are different, yet a lot more simple compared to what's in the original.
While it isn't against NG's guidelines, it's still morally questionable.
EDIT: Thanks for the <3 Benek, but you do know this review is negative.
