@Patchouli use the tag "original" when the character in the image is totally original and does not come from any anime, comic or video game. please take the time to at least tag the character in the image correctly. if you don't remember their name use "character request" or "copyright request".
With all due respect, I personally do not see what you are pointing out as a mistake. The anatomy seems to add up fine for me. Also is the personal opinion of poor anatomy really a reason to not approve of a post?
I might be looking too deep into this, but here's what the shoulder kinda would look like without the straps and hair, and my attempt at showing how it kinda should look like: https://youtu.be/cI-End5jQwM (I'm not an expert but just my own thought to this).
So the problem is that the neckline is dipping down with a downwards angle and in order it properly to connect to this shoulder here it has to an unnatural curve.
Understandable but why would his shoulder connect to her body and who is he? Why does he want to connect his shoulder to her body, sounds very lewd man!
Once again, my broken English has trolled me. as I said in danbooru, English is not my main language, and a recurring problem I have is forgetting that the term "her" existed. I'm trying to correct this, but every now and then I slip a "him".
Yup, I can't help feel noticed some "error" which make it kinda bummer. I know people just randomly posting their AI art, but hey why don't we make it into a masterpiece.
You can go on Pixiv and search for AI-generated images. And don't forget to go in settings and turn on R-18 images and AI-generated images in searching filter. To start with, you can find the link to pixiv of "artist" of this image and find, that there is not two but hundreds of images by this "author"
