Well if there's one place where overhead lighting is not needed it's here.

I would eliminate the overhead lighting. The lamps on the nightstands are plenty.

Here is the problem is you install hanging lights on the curve. Do you hang them straight across to complement the bed or on the curve to complement the ceiling?

Or you can simply install a linear picture light for any art you want to display.

Thank you Beverly- that’s helpful. I would likely eliminate the bedside table lamps if pendants were installed.

Also considered only two pendants- closest to the bedside table.

Yeah, that doesn't work either.

Such a dominating cove makes any visible lighting fixture odd and insignificant, unless it were an artistic shape of a single fixture. Even the lamps create an odd hot spot, and not sure what the sconces are lighting except providing symmetry around a half-circle wall shape.

This cove calls for, well, cove lighting. A hidden reveal at the back creating a subtle wall wash.

Also, but probably not on the menu, the furniture could complement the cove proportionally, with smaller nightstands and a taller or absent headboard.
