Maybe some fall decorations? I could see some pumpkins & fall greenery there.

How about you replace all the very small items with some larger scale pieces that work with the chunky stone and mantel? I love both the painting and the cabinet, but the painting is a bit large for the cabinet. I'd relocate one of them.

^Agree with P Banos regarding the small items. The stone has a lot of pattern so I’d keep it much more simple/calm. Nothing to the left of the fp, and consider the same amount of open space on the right. Give the fp/hearth some ”breathing” room.

i'd lean toward a single sculpture or vase, rather than the small grouping. Maybe something in brass or colors from elsewher ein the room.

IMO the space has too many accessories. I would simplify the area and repaint it.

I'd select lanterns for the hearth with flameless pillar candles.
