I would raise the drapery rods so that they are about halfway between the top of the window and the crown moulding. You have the transoms and taller doorways, and the windows end up feeling kind of squatty with the drapes hung right at the top of the frame. You can use clip rings if needed for more length. I would turn the rug the other way, parallel to the couch - it looks too small the way it is running now, compared to the width of the couch. Add a floor lamp to the right end of the sofa by the wall, and slide the couch a bit more to the right - it doesn't have to be centered in front of the window, and will give the room the feeling of more walking space move over to the right a bit. Take the tall cabinet and put it on the left side of the console cabinet, to create the feeling of a larger entertainment unit. Take the big plant off the top and add a nice plate on a plate stand up there, perhaps a pair of candlesticks or a smaller ivy plant. Take the single chair and put that on the right side of the cabinet, as extra seating. Add a lamp on the right end of the console by the chair. Something in red, either the lamp or the shade, would be nice to bring some red to that side of the room. The height of the lamp will balance the height of the taller cabinet on the other end, and also provide some warm lighting for the person seated in that chair. Try bringing in the two wing chairs and putting them at a soft right angle to one another down at the right side of the fireplace. A round table and lamp between them would be a good addition. A fabric ottoman that could act as a coffee table and extra seating would be nice in front of the couch. Something narrow and simple in design, or even a pair of the square ottomans in a bright red or rich moss green would work. The mirror is great, but too small. Try to find a large piece of art, or even a pair of framed pieces. The mirror will only really reflect the tv, so not a bit bonus to have a mirror up there. Add some taller candles in holders, perhaps the vase of grasses currently on the hearth. Once you bring the lamps in by the couch and wing chairs, you likely won't need a lot of art on the walls on either side of the fireplace, but wait and see for sure. You have a great start in the space - just need a few things to pull it together.

The Wedgwood vase is very pretty - it reminds me of the startup silhouette on the Kindle app. But the Beagles Biscuit tin is perfect! Raboo - my Lab chooses to spend part of her day and every night in her crate. And we haven't closed the gate in over 4 years. It's right in the kitchen where she feels like she's in the center of all the activity. She loves it, it's her den and her favorite snoozing place. We have dog beds in the study and family room too - but she still prefers her crate.

I can't comment on those particular pieces, but I do have a cherry bed and dresser from the Grove collection in my kid's room. It's pretty nice quality--good wood, good assembly. It's solid wood, so if you're looking for bookmatched grain, this isn't what you want. In other words, it's as nice as it looks in the catalog, with no surprises. :)

I definitely dislike the linear fireplace down so low ... and, with the flames underneath, it kinda looks like poor old Walter White's in hell. The no-fireplace option definitely looks best ... I like the clean lines, and I like the storage under the TV. BUT I wouldn't want to give it up. How about replacing the fireplace with a SMALL, unobtrusive woodstove to the right side of the large TV? Do you want a fireplace? Doesn't matter much what people on the internet want; we're not going to live there. Well, if the OP were sure of these things, he or she wouldn't be soliciting advice.
