I’m not saying you’re wrong, but I’m not seeing what you’re describing.
I zoomed in on the pic you posted as much as I could, and I don’t see anything at all wrong with her skin. No peppering at all, only a few freckles, which red heads are known for, especially on their face and chest.
Her nails are trimmed short, but I don’t know what they were like when she was in the project. They don’t look like she’s been scrubbing floors for even a week, let alone years.
The thinness you mentioned can be chalked up to the wide-angle lens. When you’re on the far sides of the frame, it makes you look thinner. It’s just a product of how the lens is designed.
She was never very thick, anyway. She always struck me as willowy and svelt, sylphlike.
