overall image is too blurred/noisy. if doing ghost via layers, try to keep the environment crisp as much as you can (obviously not possible 100%, but static objects should not be blurring like this) and give the blur to the ghost, otherwise it loses a lot of the punch
Hah, great title, there is a will helm scream app I have on my phone so it screams if I drop it.
The photo really doesn't tickle my fancy but I think I see the whole "ghost hunters" esque real ghost photo style you were trying to capture. It is a creepy photo no doubt. I just don't see it competing in an expert editing challenge.
Good luck though! Hopefully you'll find a few people who are into this niche of creepiness.
