Thank you, CB! I'm still sold on a floral arrangement next to the TV, and maybe a solid color table runner. Roobear, thanks for the help but with the tv above the big fireplace, it looks like two black holes! lol. Also, having such a high technological piece above an 18th century FP defeats the purpose. No offense to anyone, but I don't like TV's above the FP. IMO, a FP should stand alone, except for regular decorating on top of it. No large clocks. They're too trendy. I also have a nice grandmother clock on the mantel which has beautiful westminster chimes. Hockeymom, I agree. The good thing is the room is sooo big the tv isn't even a focal point. It comes across as one in pictures, but it's not IRL. Maybe in a few years when the newness wears off of the stand, I'll get a nice piece of furniture for the TV..which is what I wanted in the first place..but oh well, dh was so proud of his purchase, I didn't have the heart to tell him it wasn't my cup of tea, but I've learned to live with it so it doesn't bother me anymore. I also remember he drove all over the city in his suit on a very hot summer afternoon shopping for TV's and stands. Men and their toys. :) When we're finished using the FP, I'll piddle around with the bucket and wood stand. Now dh has his chess board sitting behind the bucket! It's nice, but I may move it some & see if he notices. ;)

I would buy the largest rug possible for the area with the sectional which will help to "pull out" the sofa from that corner. Something with a bit of color to liven up the monochromatic look of the wall and sectional would really help. Instead of red I would consider yellow or lime green pillows, and also pillows with more colors and patterns. I don't see any lighting in that corner which gives it a rather "dead" look. A tall lamp to the left of the sectional would add height to that area in addition to light. Since the mantel already has a shelf-like look, I'm not sure whether shelves are the best idea. They should at least look very different in design and I would paint them the color of the wall. That will make whatever you put on them really stand out. It's a very nice room otherwise. If you like art, a beautiful picture over the mantel would make that area more of a focal point.

I think that one is ugly and doesn't fit your space. search, "Ikea bookcase hack' or Ikea hacks for media cabinet or shelving. there are a ton of ideas. or try something like this. its a large open wall space. make it look nice and display books, or artwork, whatever. they even have an Ikea hack using Billy Bookcases that look like built ins. paint the wall a dark color if doing white shelving for a more custom look

No one looks at themselves in a mirror while eating, so if that's what you would like to hang there, by all means DO. A mirror is a classic dining room element that expands the space, reflects chandelier light and candle glow, as well as the people gathered around the table together. It's a lovely addition. Should you choose artwork instead, don't feel you must match your choice to artwork in another room. Art is much more interesting when you collect pieces that speak to you in some way; that have special meaning to you and say something about who you are as a person. Anything else and you might as well be in a dentist's waiting room. It's your home ... let it reflect who you are.
