is the table centered to the light? if not it needs to be. Did you install a new light or is this the one that was there? as far as the buffet wall. i dont think i would have the buffet there, and i would do three large prints

the buffet seems much too small for that wall, how does the mirror look on that wall? a big drum shade lamp would be pretty with your chairs and rug. The botanical prints would also be nice if they are big on that wall or on the wall where the mirror hangs now. If the buffet is as small as it appears it would be better on a shorter wall Nice room with good bones !! Be sure to post pictures.

The botanical print idea would be nice. If you drink wine, how about some pretty wall storage for wine glasses and or wine bottles on either side of the buffet area to fill in? I have a Pottery Barn wall shelf that has a rack for storing wine glasses by their stems. They also had storage for bottles at the time that are in tune with the character of your room. I just saw numerous nice ideas on their web site under "display shelves" including some that are mirrored.

I s your credenza large enough to carry the mirror you have on the adjacent wall + 2 lamps as seen in the ref pic.
Suggesting you change the prints with the mirror.
Also the chandelier would be interesting

We could use more pictures of the room. There appears to be a piece of furniture on the wall nearest us in the photo. Perhaps this buffet could move to the end wall under the mirror if it's not too short. Then you could hang your botanical prints alone on the long wall.

Whatever you hang over the buffet should take up no more than about 3/4 of the length of the furniture. Otherwise the wall looks top-heavy. But doing that with this buffet on this long wall will leave you with too much space to the right and left, I'm afraid.

This light would look good in your space:
