person-shaped creäture

isn't jpg, jpeg, pdf, or png

Is a file extension you don't recognise (this one is a visual basic file, used for scripting, but others like exe or bat are used)

has a very low or unexpected file size (this one's is less than 1KB, or 0.001MB, a good reference should be at least 500KB)

Just a little summer fun. https://topatoco.com/collections/wtnv/products/cpb-wtnv-pinata-sh

The double-stacked bricks with the line across them (one pair is half a brick over to the right of the bottom of the lower window pane) are called Shadow-Tex, at least in the part of USamerica where I learned about bricks. Aa far as I know, Belden Brick is the only company in this area that makes that texture and shape. Below is one of Belden's shadow-tex brick in a color that would work here. Maybe I'll do a separate post to explain how shadow-tex bricks are made, because it's neat. They are usually at least 11 inches long, so you'd have to cut them to make them match the length of the others (7 5/8" if the building was built in the last 35ish years, maybe 8" if it was built before that).

The rest could probably be matched with Acme Brick's Mission Trace, though king size might not work.

If mixing Belden's shadow-tex romans and Acme's Mission Trace kings is too much work, you could conceivably use General Shale's New Foundland bricks by themselves. The bark texture on some of the bricks in this blend (blended from different lines at the plant) could kinda match the shadow-tex brick from afar.

Oh and the piece above the window is called a lintel, pronounced like the legume. Concrete lintels are reinforced with rebar, so they can hold the weight of a brick veneer!

glamor failure shenanigans lead to one of her friends opening a door and mutually startling a very tall Mimikyu

when the parents arrive to help clean up, Corbeau sees The Terrifying Girl greet "mom" and he accidentally makes eye contact with Gris

Nox doing the "hand crank slowly raises middle finger" gesture

Lol oh I love all of those. Especially the second one. Poor Corbeau feeling a chill go down his spine and realizing that of course Lux is terrifying, her mother's ten times worse.

Also fun fact I actually had a thought about how Lux's friends would find out she's a Mimikyu specifically in the climax when everything's going to shit and there's rogue megas running amok. Lux jumps in front of a hyper beam to protect the group and her friends panic as they watch her seemingly get vaporized like "LUX NO"

...Only for the blast to clear. And reveal an alpha Mimikyu standing there. Completely unscathed save for the head of its disguise flopping over pathetically.

Everyone: "What the--"
