Very nice room, I'm sure someone will pop in with furniture arranging skills. I wouldn't do a rug on carpet. If you want to tie in the teal, put some pillows on your sofa with some teal in them - a print of some kind would be nice. the chair looks lonely over there. I'll be following to see what others have to suggest.

Hi Kristy- You haven't said what your style is and what furniture pieces you must keep and what you are willing to give up.

If I had free reign, I would get rid of that huge entertainment unit. It is dark and heavy and old-fashioned and brings the whole room down. We needed things like that when we had big bulky TV's, but we have flat screens now.

You can buy an inexpensive wall mount for your TV or a nice table or even some sort of attractive buffet with storage on which to set your TV.

Your leather sofa and chair also seem heavy and overscaled for that space.

Your home is spotless.

Why not try a white or off-white sofa with your beautiful teal chair drawn up next to it.

You can also get a coffee table or a large ottoman with a tray on it.

You can get some throw pillows that coordinate the teal with the green plants in your aquarium. to put on the chair and the sofa and put in a throw as well that color coordinates.

In the alcove over the aquarium you can think about hanging something interesting that is three dimensional such as a macrame wall hanging. You can make it yourself or buy one on etsy or ebay.

Or you can buy an obi sash.

Or hang a few interesting colored butterflies.

I would change the candlesticks on the left side of the mantle, they are too chunky. You can find some that are more graceful, but you are quite correct to do an odd number.

If you are going to keep the art over the mantle which is nice, please get different stems for the teal glass vase, the shapes are too repetitious. Please find longer stems, not a rounded arrangement. You might find fresh things from your garden, even live leaves look great.

I would need to see more photos of your entranceway, but I think the art hung over the console table is hung too high. That would actually be a nice spot for a beautiful mirror. People want to check themselves as they enter and exit.

Try moving the recliner to the other side of the sofa. Right now it just looks like a large obstacle in the room. Move the teal rug in front of the fireplace. Move the teal chair out of the corner and slightly onto the teal rug. Get teal pillows for the sofa. You have too many vertical lines over the fireplace. Take the candlesticks off and take the flowers out of the vase.
