You have an excellent starting point with this space. Your color selections are very nice, and the large furniture pieces are well suited. I do love the dining table with its contrasted top, and the light chairs. It is difficult to tell what exactly is under the throws, but I certainly understand the beagle issue! I would spend a little time to find some throws that are more in the color range of the sofas, that way the space can always look more complete, even when protected.
Balance- The arrangement works ok in the living area, however the dining table seems to float in the center with no grounding elements around it. There appear to be no vertical elements with the exception of the doors visible in the photos, and the art and accessories on the walls are hung too high. This combination tends to give what I call the "hat box" feeling, a feeling of a box top that can be removed or replaced at will, as the ceiling seems to be have an odd relation to the room.
Emphasis- My guess is that your plan is to have the living seating arrangement as your focal point. That is a great way to go, however (again it is difficult not knowing the true colors and fabrics on the sofas) if you choose the seating area as the focal point, it must be very deliberate. The sofa near the dining room, looks to be a medium dark (terracotta or burgundy?) in the value range of the wood doors. The window sofa, looks much lighter. For this to work you need some way to keep the lighter sofa from disappearing into the window wall. The glass tables really don't work at all, as they are visually non-existent. There are other solutions as well.
Another option could be focusing on the window, and moving the entire LR arrangement 90 degrees. This would allow for a visual corridor between the sofas directed at the window, and some additional window treatment could be added for accents.
Rhythm- Here is one of the weakest elements of the space. All of your artwork on the walls is, for the most part evenly spaced around the living room. Negative space(blank or empty space) is essential in any design. Associate what is on the walls with what is in the room itself. You have gone the opposite extreme in the dining area. The pieces all appear to float around the wall, as they don't relate to any of the furnishings in the room.
Harmony and Unity/Proportion and Scale- The objects in the rooms do have a unified feeling to me. They do feel as if they belong in the space. The furniture items feel appropriate in scale and proportion, with the exception of the glass tables, and the shelf and table in the dining room. These need to be replaced with something less fragile looking and more in tune with the substance and scale of the dining table. One more thing, your accessories all look to be very close in size, and scale themselves. This gives a cluttered appearance. Select your favorites and use them, and add some larger, bolder items.
