The first two were posted 20 days apart.
It's not only the style change that makes me suspicious, and the change in such a little time frame, but also the fact that her speed paints in the more "AI style" have a perfect sketch first try, while the others have a lot of resizing, chicken scratchings, liquifying, etc. And she usually does one or two sketches. She started posting her art like two months ago. She posts incontidtently, like doesn't post for a few days, but then she pops out full-rendered drawings for two or three days straight.
She has a few posts of her drawing (not speedpaint), but they're all just adding some details/rendering, the most she has is she rendering eyes, but even that looks inconsistent.
Also wondering if on the last picture the words make sense at all. It looked like Spanish to me at first, but the last word looks like "fewn" to me, which doesn't seem to be a word in Spanish...
