It looks dark to me. I'm on my laptop, so that may be why. But overall, it looks dark and dingy. Much like I would expect if you were trying to give a grim or foreboding mood.
I'll have another look when I get home to my much brighter desktop.
*EDIT*
I fixed my post... not sure what was up with the funky symbols?
You are right it is somewhat dark/gloomy. This is the only edit that I have like this one. For this particular photo I like it. It definitely is not typical.
