The story of how that background was created has been stated by the artist himself: he was studying in the quartier de la croix-rousse in Lyon, and incorporated it in the drawing using multiple reference pictures.

So while the neighborhood is recognizable, it is not a perfect match from any POV.

Focal length op.

I see more. The girl's perspective is further to the left.

Also, relative positions of circled buildings seems off, so I would say that this address is off by some distance making it another address

If the drawing is an accurate copy of an original photo, then that original photo was probably taken from the left of this new photo. Not a few meters to the left, but dozens. (I'm ball parking it from my phone screen)

With 3 landmark recognition points, you have enough info to properly "triangulate" a 4th position, but that wasn't done here, the angles are wrong.

• The relative distance between the buildings matter, you have to know which is further away. If I'm wrong about which buildings are closer/further, then it could actually be to the right. A phone is probably not the best device for doing this kind of guesstimation.

Contrary to popular belief, AI is very stupid BUT it is really good at finding patterns, so it’s probably already been in use for location detection for quite some time.

Maybe.

But I’m pretty sure this was noticed the old fashioned way, with our own eyes.

I'm confused is this a real person with like a cartoon avatar? I've literally no idea what's going on here.
