This is absolutely ai. Maybe traced into manga style, or placed over the bacgkround. Maybe some man hands were traced from a clip dtudion paint dummy or whatever But it's definetly ai.
Aside from proportions being completely wrong for on 2 out of 3 characters.
There is also: boob size & behavior inconsistence.
Dead eyes looking who knows where, and not on a partner intro the camera while the face very often almost parallel to the camera plane.
Hands not completely butchered by ai, but clearly from a another place. Pic 14, slightly weird, but huge male hands. Page 20 inconsistent style of man hands plus clear signs of editing on a female one (also fucked up thumbs)
This very weird "dick placement" where it awkwardly pushed by 1-2cm, awkwardly bent or somehow having a tip outside of pussy, while the composition clearly shows it being almost all the way pic 16
etc etc
You all should check you eyes, or else you'll go blind from excessive masturbation on ai shit.

Or, almost forgot. There is also old works of this author on this site with completely different drawing style. So either you believe this is work of master creator who can do multiple styles but somehow can't do consistent proportion & good composition, or shitty ai trace.

Also wtf, stop uploading this same crap multiple times, so i don't need to duplicate comments. Just make it all the single gallery ffs.

Base +7, katiga -3, master119 -6

Well, I wasn't expecting to see haruhisky/harukichi getting accused of AI today.
