I think there is a lot going on on that satircase I would maybe paint the wall a different color but that is all. I would change the light fixture for sure.

It’s a grand and lovely staircase, I think it calls for grand art as well. Family photos would be fine, but I’d have them in elaborate frames, not simple casual ones. Think of old family homes in Spain, France, Italy. Beautiful wrought iron and impressive art along stairs ... paintings and family portraits.

Of course, my advice is dependent on how the rest of your house is decorated. If it’s a very modern aesthetic, then I’d suggest more of a modern art look as well. Canvas abstracts, thinner frames for other art, contemporary mirror.

Can you show or describe the rest of the house?

I agree the light fixtures should reflect the iron work of the railing, which is gorgeous! I would put a group of black and white photos on the wall by the two flight of stairs you can see from the first floor. Leave the others blank.

How about a small piece of furniture (lowboy or table with 90 degree and that would fit into corner) on the 1st landing area?

Beautiful staircase!

I agree that the staircase should be the show. Paint the walls a deeper color. Perhaps add some large mirrors. Less is more here!
