A quick fix for the dining room would be to center your dining room table in the dining room area. You can define this room a bit more clearly by adding a chandelier centered above the table. For the living room, the loveseat can remain on where it is, but pull it away from the wall. Move the loveseat so it more to the right, it does not need to be centered under the window. Place the larger 3 seater couch along the wall where the coffee table currently stands. It should rest under the window about a foot away from the wall. Place the side table at the corner between the now perpendicular sofas and center the coffee table in the room. This will give you space for a nice entertainment unit where the large sofa previously stood. Alternatively you could place a credenza here to store your dining room dishes or additional storage. Lower the painting on the wall to eye level so the center of the painting is at 54" above the finished floor. Purchasing new window treatments or drapery panels that coordinate with a new throw and cushions for the sofas will tie the elements of the space together and make it more cohesive.

Is there something in the room you want reflected back that you love looking at? If not, why don't you find a nice piece of art work for the fireplace so you have something to enjoy rather than looking back at your other wall?

There is nothing worse than ceiling-mounted lights--harsh shadows, flat lighting. They are strictly for utility. I would put a large-ish, shallow cylindrical shade on them and put nothing more than a 15-watt bulb in them. Use them strictly for lighting your way as you walk through the room. I agree with Vincent; the chair in the corner doesn't fit at all, nor does the one under the A/C unit (put that one with its mate behind the love seat). And the curtains look smooshed. I think the problem with the bookcases is that they are uninteresting. Did you buy books-by-the-yard? What are all those identical books? They are visually uninteresting. I'd get rid of some of them and get some colorful ceramics/glass/photos. The room is absolutely overwhelmed with furniture. It needs one less love seat. Do you really need all of them? Pushing them against the walls/curtains so tightly just visually emphasizes the fact that there is too much furniture. I don't think a mirror above the fireplace will work. When people are sitting down (which is most of the time), all they will see is a reflection of the ceiling--the plain, white ceiling. Get some real art in there with some color.
