This is a successful dark pic. I can see the background buildings emerging from the fog. The top of the cab is enshrouded in mist, but clearly visible. My monitor is up as bright as it will go, and I also notice that other monitors don't go as bright and many details are easily lost in darkness. In order to compensate I always increase brightness contrast between 10-15%. It doesn't look right to me, but I guess it's better to do that than have a bunch of people wondering what is in the picture. So, since I can see your image fine, it's a sure bet that this pic would be almost black on my monitor at work, for example. I notice that this does not carry to print the same way. Something too dark on my monitor at work prints out just like it looks at home. So if you intend to print, you probably won't need to adjust brightness. If you want your work to be a "computer" work, then you might want to raise them so that everyone can see the work. In the darkest case, the picture you intended, in the lightest case, brighter than you'd like, but no harm done. By the way, is there going to be a coachman with a crop on top? That would make a nice silhuoette. I agree with SamTherapy that some kind of illuminated fog effect might be nice around the lamp.
