Your picture display looks lovely with your sofa and will look better if you bring it down because it's a bit too high above the sofa ( unless you plan to keep adding to the picture collection below from where your pictures are hung now) and in that case just keep in mind that multiple frames look best when arranged in a diamond, rectangular or square shape and spaced relatively tight, like 1-2 inches apart. A looser grouping can work for a more casual display.

A few simple steps can give your room a lot more vibe! Try pairing the drapes with sheer curtains, that will give the window more depth. The tv wall could be your accent wall, a dark blue would actually work very well. If the TV has backing, I would hang it on the wall, a few inches above the furniture piece. The two frames above the white dresser should go below the wall clock. Instead, a large art piece (about the length of the dresser) would complement that wall much better. I would also replace the coffee table with a rectangular, heavier glass and metal table, placed in the center. Also pillows. Pick up colors from your art work and the accent wall and use those to find pillows to decorate your sofas. Hope this inspires :-)

Congratulations on your new home! Now, go cancel that order! Just kidding. Kind of... I really do think, after reading your posts, that you will be happier with the grey couches. Personally, black couches in general seem very bachelor pad (ish). That said, I know there are gorgeous black leather couches available. For a super modern industrial place, maybe. But beach, or that kind of vibe? I am not sure how you would pull that off over the years. Grey or tan (neither are my own favorite decorating colors, but still) would be oh so much better as a neutral for pulling in different color palettes with pillows and art, etc. if you decide to change up through the years... black might make you feel stuck. After reading through what I have written it seems a bit funny, as black is my personal neutral in clothing, jewelry and the like. But as I look around my home there is no black to be seen. Hmmm. In any event, follow your own intuition here, and don't feel like you have to fill the space before your home is even completed. Especially if you are having second thoughts. And remember, this is supposed to be fun for you! When in doubt, leave it out! At least for the time being.

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.
