I get the dark thing, absolutely, but dark shouldn't mean blocked up shadows. You can have a very dark and menacing image, but still have it look correctly exposed. Simply darkening an image is, ironically, the worst way to make an image dark. careful use of curves and the histogram can make an be read as dark and heavy, but still have a beautiful tonal range. This image just has areas of black nothingness where shadow detail would have been.
I also suspect your monitor is too bright. It;s not as if there's anything in those shadows that strikes a chord with my subconscious or my hidden fears... I know it's just a bunch of leaves and crap. The other dark area on the left is just the fence... again it's not leaving anything to my imagination at all.. it's just a fence that has lost of shadow detail due to aggressive processing. There's no menace lurking there
It's too dark dude.
So any reaction is a good reaction? I just don't see why you wanted anyone to think the man in the shot was the vandal, as that's what the title is definitely doing. If you'd merely called it Graffiti... then no, it wouldn't. Adding the noun Vandal, makes the man the subject of the photograph (and title)... not the bench. Surely you see that.
