I agree with Jordan's idea, but I would use dark wood, lower matching consoles, and I think I'd put a display of crystal and/or silver on each to reflect the light from the chandeliers.

I would be looking for a silver leaf buffet or silver leaf console. I think your art is lovely but with your ceilings you could go much larger with a great piece of art. :) I wouldn't get a mirror because it looks as though your kitchen might be right across so art would be the the best option.

Wall paneling would help visually, and either a bigger picture or a gallery wall, I don't think that photograph suit that space.

I would put that piece of art somewhere else and get something much larger and for sure i would add a buffet but i would use the darker wood for it IMO you have enough bling in the space

Jen's idea is very good or perhaps group a huge pictures of four or mirrors of four (grouped) then a short but long mahogany cabinet under them. Or just get a huge (tall) glass mahogany cabinet and push it against the wall (where you can store and show you collection of cutlery) ;)

You can try wallpaper.
