Pull your furniture away from walls and unto the rug, love your furniture and rug. I am not a fan of this kind of triptych art, it's too choppy, maybe hang them really close together without any gaps. That's what I would do.

this wall art does not work over the 2 chairs.They would look better over a single piece of furniture closer together as AdAD suggested.

That's what I was afraid of... Can't seem to find something that works in this space unfortunately. Should I go with one large piece? A shelf with other pictures hanging?

More pictures of the whole room would help. From what I can see, too much blue going on. I would like you to find a larger art piece first thing (maybe something else from around the house?). That can be your start and it will tie in as long as there is some blue in it.

Looking at the room, I think you should pull chairs away from the window some. Change rug to a shaggy cream and add curtain panels in a cream also. Chairs should be partly on rug.

Dog seems to like the art. Is he staring at it?

I think a large framed black and white photograph in white frame with glass would be wonderful, or several..

Really big, 36"width and up...

Actually, with white curtains, rug would work fine. I really do want to pull the rug away from the window some. Do the chairs face a tv? Otherwise, maybe you can arrange to look out the window. If the room is dark, might want to hang a mirror. Maybe one framed in white to tie in with the rug.

A picture of the whole room would help. As others are saying, I think it is the furniture that is not quite right just yet and then worry about the art above it.

and this can be a picture of your dog, or you, or children, or your house, or even your house interior (conceptual :))), take a picture with a high resolution, have them printed at Staples and pick the frames up at Michael's:)

A large rectangular artwork would work. The 3-pieces would look better above a 3-seater sofa. I support the suggestion to pull the chairs away from the wall.

Rug can go, buying this coffee table

I like them on that wall and suggest moving the sofa under the grouping. Switch the sofa and the chairs. They work well with the sofa and the rug! I feel they work well and you don't need exact match with colors. They're great with your fabulous rug. Hang them about 3" apart from one aonther and level. I love the rug. Where will you put it?

I would tilt the chairs in word a bit to slightly face each other .... If you keep them where they are

Biggest impact will come from addressing the windows: as mentioned higher, wider and better rod.

Other good advice from Aggie: round glass piece on white shelves and large black and white photos of your family would add tremendous amount of personality to the room.
