Thank you for the comment and your kind words!
Hmm, it is strange
This is the last puzzle I fixed, so, as usual, it might unexpectedly break again(
But I checked it and it was working fine.
Could you send a screenshot of the mannequin?
Oh, sorry, I already suspected that it was broken for some reason :)
I will send you three hints with different levels of obviousness. There is no spoilers, so read carefully!
Hint 1: Mom really likes her, and wants her to stay forever as she remembers her in her day of triumph.
Hint 2: You can find details about her face in the newspaper. The newspaper also contains a password for the camera somewhere. If you use all this information, along with one more piece of information from the camera, you will solve it!
Hint 3: The newspaper contains the phrases: "clench her teeth" and "looking ahead with wide, clear eyes". Since the newspaper features a photo of the sister, you can see her hairstyle. There is also a date on the article that doubles as a password for the camera, allowing you to see what she was wearing on that date.
