There isn't enough distance between them for that to be a factor, and even so the door would already have to be enormous to produce that effect. In short, you can't make an object behind another object appear larger than an object in front of it via any kind of optical trickery. That's not how distance works. You can make your foreground object appear larger relative to the background object by playing with foreshortening, which is exactly the opposite of what's being proposed here.

You can do the thing with the moon at terrestrial scales and distances because it's the size of the moon, and very far away. Since the apparent diminishing in size of an object is roughly geometric in relationship to its distance from you, how far away you are from a terrestrial subject (say, a person) will influence the apparent size of that subject much more than it will the apparent size of the moon, which unless you own a rocketship will always be basically the same distance away from you proportionally speaking.

I don't think that is how zoom works (without severe lensing artefacts) - the size of the moon compared to everything else stays the same, its our perception of the pic that changes.

Eg - the moon is still the same width compared to the hill in both views:

Yeah they could've been on a neighboring building and zoomed in to take a picture of a single person holding a sign.

Or they could've just generated an image.

With the blurring and weird repainted wall way and way the text is all lined up nicely almost makes it look like a classic photoshop but I'm no expert either.

JUST look at the shit behind her legs on the sidewalk, its so fucking wrong
