Your space is mixed with a few different styles here. Farmhouse chairs and table, the tablecloth also screams farmhouse or cottage. You have a somewhat traditional or MCM glam chandelier that looks off centered or the table is pushed to the end of the wall.

Move the table more in the middle. Or is it in a pathway?

Then, get rid of those small paintings. You can either get 3 large identical frames and put the photos in there or put them elsewhere, in a kitchen etc.,

The world is yours! You can wallpaper, paint or simply keep it the same color and just put the frames up.

Simply removing clutter, painting the walls a happy yellow and straightening the paintings can work wonders. I still suggest framing the photo prints and lower them, if you really want to keep them.
