Here’s the wall mirror for the back wall, and detailed photo of the lamp

Mirror is large, 46”x78”

What is the mirror reflecting? I would not put a mirror there as it would only be repeating white walls, reflecting the glass light globes and make the room seem even longer. It would not add anything to the room. I would put a taller painting to balance with the windows. Also I like the bronze lamp colour because it reflects the darker elements from the kitchen however why put a lamp there as there is no chair for reading etc. I think that is a better location for a plant or a tall sculpture .

I like consistency among lighting fixtures. So, will suggest that you match the metal finish on the chandelier in your dining area. Will also suggest that you replace the fixture in your living area to match as well.

Brass. I would keep the art and no mirror BTW.

A tripod lamp would suck up floor space and I dont think its the right lamp or mirror. I would not put a mirror by all those windows I think it will look like a wall of squares and one does not fit...
