Taken in the British Museum, if you've ever been you will know that it can get very busy but for just a brief moment this couple seemed like the only people there!
This was a totally unposed shot. I never spoke to either of the couple and they were totally unaware of me and my camera.
I like this shot a lot. I think previous color comments are correct -- I would warm up the shot to counter the blue/green cast. I love photos that have a huge architectural scale with people dwarfed by a large building, but in this case I don't think the large scale adds to the image. If you crop out the ceiling, it would simplify the composition and draw even more attention to the couple. But I'm being picky because you asked for a critique -- this is a really nice photo as it is.
Too OOf to me. if maybe you could sharpen the couple and mask the rest maybe even make them stand out with some slight dodging over them. not enough to notice but just enough to draw the eye. Right now my eye is drawn to the roof area at the top. HTH
Yes, the colour balance is certainly off. But I'd say too green, not too blue. Take note, I'm on an uncalibrated monitor at work, but that's what I see.
The stone looks a little blue to me. Other than that, I don't have anything helpful. If you could have posed them, I would put them right at the first step, next to the wall on the right.
