One more pic of the bar area to get an idea of my style. Thanks!!! (I do use color, just haven’t in these 2 rooms yet!) lol

Pratime, do you mean the extra kitchen base cabinets that are under the window and extend to wall with sliding glass doors? Two sets of floating shelves on either side of the window and above the tile backsplash would allow you to display decorative vases, candles, art, a collection of objects meaningful to you, etc. And a painting on the wall with the glass sliding doors.

Agree with lynartist get someone knowledgeable in to look at the walls. Shifting the color used makes a huge difference. I would not have the walls smoothed or made shiny. But there are all sorts of ways to approach this and end up with a great looking home. Consider moving the functions of the two spaces. A modern dining area with a fireplace, even such an ornate one, could be spectacular and marry well with a more intimate USED space for conversations, drinks, and even just solo book readin'! Making the switch would also de-emphasize the fireplace and allow it to look its very best. A bit of a paradox but look at many old European houses and you'll see it again and again. My other preference would be to have a wood refinisher take down the shine on the floor. Congratulations and I hope you let us know how this progresses.

Real solutions. : A longer side board unmatched to the table. A new light for over the table. Perhaps a different rug . The bottom line is the room should relate to the rest of your decor, and we've no idea what that is. We're seeing what you are seeing. A sallow wall color, a dim and sad amount of light......a blank wall. ......a printer and toy storage. Appears you need more storage, Whatever happens above that storage is dependent on it's size......length. It depends the rest, and your budget etc length matters ...............
