>>4607795Generally people just say they're overworking a piece. I don't know if there's a word for the specific mental state of not being able to judge quality any longer though.
My advice, if you find yourself in this state, is to put the piece aside for a day or two, and look at it with fresh eyes.
If it looks done, it's done. If you notice things that are wrong or could be improved, finish it off. Usually this won't take very long; it's mostly about making things "pop."
