Sorry to say but thinking it's AI. You can find more on Insta, @amlaurakristel
but looking through the photo's they all look like morphs and poses from Leicht Perlig or at least they programmed their AI modeler to use her as reference material. Sorry for the low res but here is a screen grab from a video clip of Leicht that almost matches the exact pose, body shape, hair and background of your photo. There are obvious differences between the two but it is amazing close as well.
