One way might be to use a hue/saturation adjustment layer and target the blue-magentish reflections
which is present in the carpet near the wall plug as well.
If you photo is a camera raw file, probably most of the corrections can be done in camera raw before going to photoshop.
I hate to be a wet blanket, but I see nothing wrong with having the bluish-white reflections in the image, but of course that would depend on your need/use for it. Having no reflections at all would make the backdrop behind the crucifix look dull instead of shiny, and I find that overall the image loses something if it all is made kind of warmer/yellowish.
Sometimes I test my point of view by actually following my advice (or what I advise against).
I think I was wrong in my post above. Just some ideas, letting the creativity flow...
- Healing Brush Tool to paint out the light highlight reflections in the marble backdrop.
- Cloning and Healing Brush to remove the electric fixture.
- Color Balance to darken
- Lens Correction, Vignetting to darken the outer edges.
- HDR Toning to help bring out the dark wood.
- Some Burning to darken the frame around the backdrop and the walls.
- Selective burning in green and blue channel to warm still too cool colors.
- Some effects on the lights.
