And remove the cacti from the table.

Agree with Kate. Your home needs curtains to give texture.
Put your family photo that is currently on the wall, in a frame. It is just too plain, on canvas for that spot. Maybe a white and gold frame.
Remove the "mother in law tongue" plant from the table. Purchase a pot stand and put it on the floor.

Very pretty room, artwork lovely, I would add more texture in your cushions instead of all solid in colour, have a look at Adairs, some beautiful pieces at the moment, Pier 1, Habitania, anthropologie, yes just throw your throw, looks better than folded as suggested.

With that lovely couch I think neutrals would look beautiful instead of pastels and would bring the artwork to life.

Placement of the furniture looks great. But agree it needs texture. I think the single biggest thing you could is add curtains to layer over the roller blinds. Then change up the cushions with some neutrals. Also, the mother in laws tongue plant on the dining table is too tall and skinny. Better placed against the wall.
