I wouldn't add pink. And I'm thinking about replacing the coffee table. Otherwise, it's a very pleasant space.

Nice room! I recommend color. You might swap deep clay/rust or warm brown velvet for the pink. Warmer tones would be a bridge to the tone of the floor color and also repeat the tones of your kitchen, giving a better sense of flow. If you love the pink, keep it and add a visually soft squishy larger deep jewel plum tone pillow or throw, especially on the graphic chair instead of the white pillow. I think you need the repetition of fewer larger accent items for balance as your sofa and fireplace are visually larger scale. You have lots of good basic pieces to work with. We are plant mad at my house; a large, bright green plant might fit your vibe? (The newer comment by Celery shows green accents. I really like this even better than the idea of clay or rust or brown. She put a green pillow on the chair near the dining room. And there is a larger rug in a white tone. I think the larger rug works great. All in All, Great suggestions from Celery!)

Please, no pink. And better chandelier.

I think your room looks very nice indeed as it is, without tiny, timid pink items.

But if you want pink, then commit to it and add substantial pieces. Pink and grey can absolutely work well together. Right now they are not working for you because you aren't really using the pink. I would also consider adding larger red wine colored items in the same tone as the pink. I think that would mean the same undertone of blue, but those with better color smarts here are welcome to correct me! You seem to have some tiny bits of wine color already. So the problem, in my opinion, is that you aren't making a statement. Be brave! Be bold! They're only accessories, they can't harm you.

I also like @oliveolivehouse's idea of plum with pink. That would be lovely. Green and pink also work well together. You would still want to get the "right" pink; that is, one that works with the undertones of your other colors.

Not sure how you arrived at pink as an accent color. You already have a great color scheme put together. I would add the caramel color to make things more interesting. Also some accents in Black always add drama to a room.

The picture over the sofa is mounted too high

The mirror reflects the light from the window and IMO a large canvas would be better.

Here are some options. Your area rug is too small for the space also.

The pink seems added for no reason. Give the pink some context. Instead of the mirror I would add a painting with pink in it so your pink accents make sense of where it came from. Vary the shades of pink as well as they seem all the same tone. May I suggest you remove the ceiling medalion as it makes no sense to the house or decor.

There's something about the pink color and your flooring that just doesn't seem to fit.

I had to look for the pink, so it needs to be enhanced by multiple layers. Other things. Move arch lamp to other end of the sofa where you have no light - you already have two lamps on console table between chair and sofa for reading or ambient light. Is the medallion to cover larger hole in ceiling? If you need a fan, choose white that will blend in with ceiling. So many small items that aren’t related to each other except they are all white. Set aside 1/3 from each surface to change out with others when you need a refresh. Not all items need to be out at once. Coffee table stands out because of finish.
, have you considered a black or glass coffee table? Not trying to be nitpicking. I too tend to set “favorite” things all around, then realize I am not telling a story of my current house and life, but a story of the “collectibles”.
