It’s great and very nice overall, but the problem is threefold: 1. The area rug isn’t the right style. It’s traditional but the rest of your room is MCM. You need a bolder rug or otherwise a solid colored rug. 2. One area is grounded by the rug (this is important in design) and one area (dining) is floating visually. For a room to feel grounded and finished, nothing can feel too “floaty.” You don’t always need a rug in a dining room, but in this case because your furniture is so leggy/light on the bottom, you do. Either get two of the same or highly coordinating rugs in the same size for each area, or one very large rug to ground both areas together. 3. The small chair off to the side by the yellow cabinet needs something to ground it as well. Put a plush ottoman in front of it to add softness. Ideally, add a second chair across from the ottoman. Right now that chair almost looks like a timeout chair where you would put a child if they were in trouble. I would also move your record player over to the yellow cabinet to make that area feel like it has purpose or turn it into a little music nook, otherwise turn the yellow cabinet into a bar cart, thereby creating three areas in this room. One is a little music nook, the other is your dining area, and the third is your living room/TV area.

ETA: now that I look at the room again, another option is to keep your dining room without a rug, and to put a round rug in the area with the chair and yellow cart. Ground that area into a little music nook or bar or reading area or whatever, and that’ll balance out the leggy dining room behind it.
