The dark and moody colour can be done in Photoshop of course.
But the lighting has to be appropriate. I mean, Photoshop can enhance the shadows to make them moodier, but the shadows have to exist in the first place.
You're still missing the point.
In your photo, there is NO light in front of the guy, apart from very vaguely reflecting light.
You need to find a backlit example photo.
Ok, no worries. In that case can you find a link to a photo with the same lighting as yours? In shade on a sunny day?
Preferably with some sandstone buildings if possible.
