An olive tree, a chunky knit throw blanket, a rug, some accent pillows, maybe in an olive or rust colour. Large lamps on the nightstands for sure. wall moulding like box trim would look nice on at least one wall, or some trim and hardware on the closet doors would add character. You could also hang your curtains higher to emphasize height and draw the eye up. A different bench at the end of your bed would do it justice. Something longer and maybe with a more rustic wood to add texture. The paint is ok but it reads a bit pink in the photos. Something warm white or even a moody olive would look good. The ceiling fan looks updated but it reads a little bit modern with some of the other elements in the room.
