Do you have photos from different angles? Because there seems to be carpet and upholstered chairs, I'd use 'hard' rather than soft (e.g., fabric) items on the wall. . . perhaps a combination of mirrors (depending if there is a window on the opposite wall) and artwork. Definitely anchor this grouping with several sizable pieces. The cute table is way too small to be used here--try it behind a sofa or on a shorter wall.

I would suggest removing all of the items to another area...they are lovely but get lost in the expanse. Then get very large artwork (canvas wrapped it usually affordable) and let it take center stage on this wall. If you found two or three pieces that work together that would be nice, too. Don't be afraid to go big and really make a statement!
Good luck...let us see the "after" photos please!

You seem to have it painted as a focal wall and then give nothing to focus on. Need something large and / or impactful to justify it.

The clock is too small for the wall. It makes it look like a postage stamp. A large picture or mirror & chest cabinet,lamp & chair. Maybe a small bench.
