Nice sofa, just needs a few more touches.

Since you already have a nice wall design

I'd place a large abstract painting or large mirror

over the sofa. A accent chair, blue, white or gray.

Try a new area rug blue. Don't forget some nice pattern throw pillows

Banana plant in the corner where you have the white floor vase.

Or a modern floor lamp. This is just a sample living room I did

Can we see the other walls of the room? A pic in each direction??

Wall art above the sofa is too small for the wall.

here is some option with gallery wall arts

Imo a large shelf like the one celery showed should go on the wall we can’t see at all (if the door won’t hit it). I would like it better there because where it is in the rendering could make things feel a bit closed off when you immediately walk in the room. I think we need to see more pics!

It is a bad light right now. I will take more pix tomorrow morning and post. I loved all your suggestions! You guys are so creative!

I love the abstract, neutral rug that @Celery. Visualization, Rendering images posted!

Have you rotated rug [wide as the sofa]?

would desk/chair be apart from rug's edge/ or move them down a foot?

I looked again at your photo [is it paint, seems lovely] - and thought I saw washes of golden mustard like the rug.

If not solid, what about :

Thank you all! Here are some more pictures. Seems like I definitely need to change my rug for something bigger! Sorry, I just can’t get the light to work with me on the other side..

Someone asked what wall treatment this was. It is a custom paint work. The lady just used her color talent to make something work for my sofa. I loved it and it was not expensive.

What size is your rug, and does it work with chair movement?

The rug works very well with the chair movement. No problems at all. The size is 5x7, and I admit it might be too small. I reused it from another room.

Ok so there’s two doors. That means no room for storage along the wall opposite the art. I’m not a big fan of the desk with the other furniture in the room. It’s a bit red and could be a little more contemporary. I also think you could use some more storage in the desk although not a ton more, cause too much will make it look clunky and this isn’t a huge room so you’ll want to avoid that

This isn't to scale, but an indoor wall fountain like the Reflection Creek Fountain would look really beautiful.

Because it is natural stone, the variations in the stone background would look really nice with the wall color you have. Water sounds are also very soothing and lots of office spaces benefit from that mild "white noise" that the water produces.

I think the rug could more impactful and complimentary. Suggest as well adding light accessories

Doesn’t hurt to have storage and a credenza would be a good addition, plus it will look great

Have you tried you desk facing out?

I prefer to face the windows when I work :-) Credenza will likely make it too crowded, but I will consider now a different storage for the short wall facing the desk by the window. I now have a small file cabinet there. I absolutely loved every rug suggestion here!!!
