Scott's Creative Home Fireplaces should have chimneys. The window not needed. Consider leaving the blind closed and adding a large piece of artwork to cover the window. Use a simple frame or a canvas wrap to minimize the weight of the piece.

lpiemonte Pretty room! I love your navy and white/cream.
What is your view outside the windows, can you post a picture of them open?
Thanks!

parrotheadchic I love your start to the room. I think that plates on the sides of the fireplace in solids colors from the pillows would be great. I also like the photo below for the height from the stand maybe an option for you. For blues check out House of Turquoise.

abockhorst Thanks for all your ideas!

groveraxle A single LARGE piece of glass or ceramic--sculpture or platter--in your colors would look great.

abockhorst I love the overlapping wall platters!!

Kelly I would definitely add some earthiness to the room....there is a lot of white space. An area rug is called for near the sofa...take your cues from nature. Vary the shades of blue and green with natural, beachy wood tones. The window over the fireplace is a challenge. Upholstered chairs are needed to create coziness. I would choose a fabric with a natural fiber look to it. And then carry your throw pillows over.

groveraxle @abockhorst, I'm having trouble finding on houzz the exact piece I would put on your mantel, but my thought is you should take down the two blue vases and use a single stunning piece of glass art. Something like one of the glass plates shown in the groupings below:

Dytecture I would introduce other colors to the room.

groveraxle A strong sculptural piece:

abockhorst groveraxle - thanks for all the research and pictures. You are the second person to suggest a glass sculpture. I think it would look beautiful.

ShamikoDesign Your space seems large. The patterns and colours you choose seems contemporary, modern n bold.. Almost neuvo Art Deco ... Decorating the mantle is the last thing you want to touch when the bigger things need to be solved.
It is either your carpet or your sofa that needs to go... Some contrast is needed here. The Color scheme from what u selected - dark blue, mustard, lime green, white. Add elephant grey, black, silver to complete the look.

Here goes a complete 180 change... Are you ready?
Paint the back end wall... Cool medium Brown, that will compliment the patterned panel.
Change the curtain panel blue instead of white. Matching fibre of course,
Sponge n distress your mantel - dark brown over the white .. And add matt silver leaf over it. That will give it some pizzas!
Please change the fabric of your sofa to some darker brown, dark grey or new furniture with modern lines.
Rearrange your furniture so that it is more cozy n around your fire place.
Now for the mantle...
Add white animal head to the mantle itself either 3 small ones... Depending on your proportions
Or a large moose head over the mantle.
Balance off with two vases of ostrich feathers and silver n brown branches. On each side of the head and .maybe add your favourite books or b/ w photos - enlarge of your family...in interesting neutral frames

There you go! One option of a complete look in loo of your fabric you chose!
Cheers!
Btw the moose head is from Z gallery! It's the latest in thing now! White head... U also can find cool accessories there.

groveraxle @abockhorst, until you find the perfect piece for your mantel, I would remove one of the vases, put a few branches in the other vase and move it to a point one-third or two-fifths of the way from one end of the mantel.

Carrie Since your piece would have to be "freestanding", I'd suggest a large, round shield on a stand for that space (similar to the one below). I like the items and colours you have and will be better with the larger scale chairs that you are getting.
