Maybe you aren't as creative as you would like to be, but you probably know what you like and what you don't like. So that's why you should get a bunch of magazines and on-line pictures to start seeing what speaks to you and what doesn't. We now know that you don't want orange. What other colors don't you want/what colors do you love? Do you have a Calico Corners or JoAnn's nearby? Try browsing the fabrics and figure out what and colors and patterns you like: stripes/plaids/polkadots/floral? This is where you can start, and then we can work from there.

Sounds like you and hubby aren’t on the same page. Buying a table, without ability to return is red flag to me. He bought that rug too without your involvement. The rug is wrong size and style. No photo of the table. But better sit down and talk about this and reach some compromises otherwise, these situations can fester and get ugly over time.

Curtains would be a good idea. Even though you have blinds for privacy, curtains make the windows look finished. A little eyeliner besides the mascara. I would not do a colored curtain here. Curtains are just to darn expensive to have to switch out when your color palette changes. I would suggest white or off white, whichever you prefer in a silk or silk-like fabric, and get a marvelous trim for the edge. The edge trim can be in a white and black or whatever color you want to take from your rug or elsewhere in the room. I would not do a curtain trim in gold here because I see 4 windows, for 8 panels, that would be a lot of gold. You want tasteful gold embellishment in a space, not Liberace in Las Vegas. Here are some examples of trimmed curtains. Buy the plain curtain, and then buy the trim of your choice, and buy extra trim to embellish throw pillows, and buy coordinating different scale trim for other throw pillows. Another curtain option is a white curtain with a subtle pattern woven or printed on it.

Let's begin in the foyer, and let me know what you think about these ideas. How about exchanging the table and mirror for a shoe cubby similar to this? it holds 12 pair of shoes and is about 25" wide and 27" high. Then hang a tall slim mirror above it to draw more light from the window into the dark foyer. I love your blue art! Do you want to continue with that blue as an accent? How about adding another color that is its compliment; thinking orange for a pop. This contemporary rug is 6 x 9 so it would be slim enough for the space you have available between the armoire and the sofa. Just place the front feet of the sofa on it and I think it will work. You can tape it out with painter's tape to see how it might fit. Continue to mix your styles with an IKAT pillow featuring the colors. Here's a solid you can have monogramed Not sure you really have room for a coffee table, but this bench could float in front of the window between the two built-ins. You could move your chair left of the sofa, floating to face the window. Here's a mirroor that is slim enough for over the shoe cubby and tall enough too. The pattern adds another layer of interest.
