This space has been focused on storage. Adding a 'soffit' above the PAx wardrobes will be a finish building them in. The molding above the window wall at the ceiling can be replaced by nothing or whatever works to finish off the ceiling to PAX wall. Because you have other areas of your home, I'd look for other places and/or lessen your things to store. d like to consider removing the mirrored wardrobe and the storage at the wall with the door. Space in a bedroom can be a benefit to your relaxing in the space. I'd remove the structure above the window, also.

As alluded to above, your bedroom has a 'pantry' aesthetic.

Smaller bed?

New bedding, trim above cabinets as mentioned, bougie wallpaper, and a chandelier.

Seconding what dan1888 said - make the PAX wardrobes more like built-ins by adding trim/crown to the ceiling. Also agree with removing some of the cabinets if you are able to move contents to a different room.

Also what chicagoans said: Easy change would be bed linens. To me, the dark beddings, dark light fixtures and dark wall print provide too much contrast to the light-colored walls/cabinets. It will feel more tranquil if you use a lighter color - plain or will smaller prints. I would pick light blue but that is very personal. Pick a "lighter-looking" art print for the wall, and maybe brass light fixtures. If changing light fixtures, you can also change the cabinet hardware to a similar-looking metal as your light fixtures.

If able/willing to change bed, smaller bed as what res2architect said. If you don't want a smaller bed, I would pick something that does not have a footboard. Or something that looks a lot less solid than what you have now - like below but I would use a lighter-looking metal.
