Neutrals are quite hard to decorate with, they pose no less difficulties than color, if not more..that's why it's hard. (Wood stains are easier. Not all of them but most of them. That's because we really see them as neutrals-lots of trees around)) Fabrics and paint..yeah, we consider such and such neutral yet it still bosses us around to a degree. They are warm, cool, light, dark, whatnot But. From what I see you like both earthy and luxurious elements..am I right? I think if you pull colors from your living. Light ones, whites, color of the sofa, colors of metal in your dining chandelier..And you translate it into textiles. Fabrics. But make them as earthy as your furniture-bigger and with a lot of texture, different texture, Yet a bit luxurious as well. Say faux fur. Add a throw, couple pillows. Go for different textures. Don't make these skimpy..should feel comfy, and break the expanse of furniture. And-you should love it. Really want to use it. It's about the feel as much as it is about decor. You can add an accent color you love. Actually you can add many. Start slow and see where it takes you. Just be generous about different textures, and sizes of things. Not a lot of small pillowsbut a coupe of really cool ones. Along these lines. Put books on yout table..if you like them of course. Or a tray. Bring in plants. You can add a rug, for interest and pattern and fun. You'll add curtains at some point, I suppose. You'll add art-no need to hurry. As you go you can decide to move pieces..say an ottoman, a small side table..you'll become more relaxed, will play with placement more, will add colors, will decide to substract colors. You'll figure out your comfort zone, I love your bunnies. The ones on the dining table. I look at them and see a sort of a clue. They seem cozy where they are. Is there a bird cage in the corner? It is intimidating indeed to start off..and no place can get done in a day, unless it was collected for years (or painstainkingly designed in advance like it was collected for years) and then you just called movers. (and even then will need tweaking and thinking and whatnot). But as you go you get more like a bird or a bunny:) More carefree. You start enjoying. You make mistakes-well it's not an open heart surgery, you know. You tweak it, you play with it, you have fun, in the end of the day.

Some more pics

more pics to show what's on the other side of the wall. powder room, pantry kitchen and dining room kitchen is almost done

Looks to be a contemporary sofa and a traditional slip covered chair. The wall treatment is not at all contemporary so you'll want to paint. Put the sofa on the longer wall with contemporary art hung 5" above it. Center TV on the shorter wall on a low contemporary credenza 25% wider than the TV. Angle the chair at the window. Either a coffee table or end tables should work for the sofa, and the chair will need a lamp and table. Anchor all with a rug that is modern in style and adds color.
