Suggesting you have enough going on with all the the photos…maybe just more railing and a more important light fixture at the top of stairs. Love the photos...

This light! Love how it shines up on the ceiling and will work beautifully with your black stair railings.

If I may, not loving what’s on lower staircase wall.

Leave it as is. Not every single wall/space has to be filled in, otherwise it turns into horror vacui.

Love the idea of the light! And yes that picture tri fold isn’t staying. I’ll be replacing it with a small ledge and a few more picture frames.
