Not overprocessed at all, assuming it is for an ad that targets Morticia Adams.
(Sorry, that wasn't very nice, but I'm feeling snarky today, and I know you have a sense of humor. You do, right?)
It may be highly processed, but I like it. As long as you achieved the look you like, it goes. Except in a basic editing challenge. I can see envision this in use in the window of a trendy store at the mall.
I gave you a comment but should have asked you the question here. The shadows in the lower right.....did you add those in the PP
kinda sorta, she had a hand there and when i was darkening it , the hand sort of looked like a swamp thing. So messed about a bit with some lights and darks and came up with that, it is 03948520943 times better than the hand!
I think processing is very fitting. What bothers me though is the busy black thingies on her dress. Almost looks like some creepy beetles crawling up to her face. I would crop them off completely and kept the face and the shoulder only for a clean glamorous look in a square format image.
