Squirrel has made excellent points as usual. Also, by hanging it a bit closer to the cabinetry, and leaving a bit more space above it, so that it is NOT centered vertically, you will make the ceilings feel taller. The width of that pix seems great, and a couple of lamps on either side could finish the look. Before you decide that, tho, what other lighting will be near the buffet - do you have recessed lighting there? The reason I ask is that if you put a buffet light on either side, the center of the painting will likely not be adequately lit in the evening. You might want to do a large picture light if you don't have directional recessed lighting, and then use candelabra instead of buffet lamps on either end. Or, you could be daring and hang the art more to one side, and then use a much larger lamp to sit in the empty space. Might be a more interesting look, depending on how traditional or modern your space is, and what if any lighting that is already there.

Everdebz, to answer your questions... I don't know how big my dining table is (I haven't seen it in 1.5 years). It seats 6 comfortably or 8 if you crowd the ends. I prefer to keep it to 6. Yes, I am still looking for large scale, abstract, minimalistic art in any colors except red and yellow. I especially like black (if there was a darker color it would be my favorite), grey, dark to medium purple, and dark or rust orange. I'm not a huge fan of whimsical or fantasy. I wouldn't do 3 paintings to make 1 or have something that yells modern cliche to me. I would say I have a thousand dollar taste on a five hundred dollar budget, every time I see some thing I love, I wish it were about half the price. I do understand artists and art dealers need to make a buck but I think my expectations thus far exceed my pocketbook's depth. :)

When the striped chair arrives, angle it in the corner by the bookcase and use a floor lamp at that outlet. You'll have a reading nook and be able to flip on the lamp when you enter the door at night. I would move the TV to the sofa wall hung just above a credenza that is 25% wider than the TV. You might want to wall mount TV on an articulated arm or set it on a swivel so it can be adjusted for best viewing. Add art no wider than the firebox opening above the mantel. Pull the two swivels and hassocks a bit forward from their present location.. Facing the slider view, float the sofa & coffee table behind the swivels. Anchor the two seating areas with nautical feeling rugs that don't necessarily have to match. See if you can place a sofa table behind the sofa and add a battery lamp to serve the two chairs and sofa. You may also have room for a pair of smaller scale chairs at either end of the coffee table on the view side of your double seating area.
