Try removing the cornices from all the windows and doors. Then remove the black curtain over the doors. Leave them off for a couple weeks. Add two or three fresh new plants while you are considering your options for new light colored curtains.

To lighten things up more, you could also remove the black iron decorative pieces on the walls (you'll need to remove them for painting so you'll be ahead of the game) and tables. Put them aside for a couple weeks.

Are the dining table/chairs in view of the sofa area? I think that your stark white dining table is too much of a contrast with everything else. I would opt for a darker table and maybe a darker chandelier, too. Does your table have to be angled? I think that your living room rug works well with your sofa/chair, etc.

I have never been a fan of cornices so I would remove them. I would prefer simple drapery panels instead.

Is the " bar" used for a quick bowl of cereal or is it a booze bar? If it is used for drinking I would remove it completely. Again, it is something that I do not prefer.

Agree the table should be black like the chairs. Remove the red art. Paint chandelier black. Area rug should be larger not smaller. Legs of sofa and loveseat should be on the rug. I'd remove the bar and add a chair, floor lamp and side table for a nice relaxing area. Remove the dark panel on sliding door, you could do solar roller shades on the slider with a wood cornice to match the trim to hide the roller

Thank you all. Yes, it is one big open concept, including the kitchen. The table is off white, so is the Chandelier. The bar will remain.

this traditional style would look great, if you like black iron, with clean whites or cream, touches of gold / brass

But if you are not wanting to paint, then I would suggest trying to make everything look more cohesive and intentional by having repeat touches of of black detailing such as picture frames, curtain tie backs, chandelier etc
