Error: Badly aligned facial features; mostly the eyes, but may have to do with the positioning of nose & mouth as well.
I looked at the artist's gallery; some seems to have farther-apart eyes than the usual, but for those cases I can see it as their artstyle. This particular one just stretches beyond what I can (personally) call as acceptable in the eyes/nose/face alignment, even with her looking up is considered.
Pardon for the flagging though, that might've been too much a stretch as I didn't mean to get the image removed/unseen from search results.
