flip the sofa and the chairs.

put the mirrors console behind the sofa to face out into the step down.

move the big map to the back wall where the chairs are now.

move the black and white to where the map was.

pick one college grouping or elements from both to the window wall.

turn the rug the other way

move every thing to the center of the room.

you may not have to flip the sofa to the back side, once you center your furniture..

the yellow is nice in the lamp and Asian pot. but not too much because it is already on the walls

get your self some solid gray curtain panels. and maybe some shears.

not sure about the mirror.
