Can you give any more details? What’s your budget? Looking at the picture I can tell you need a bigger rug. Your chairs shouldn’t be half off of them. Maybe find some artwork for that empty wall. You could always update the flooring, or even paint the walls considering they’re just white. Another thing I would do is get rid of those blinds and put up curtains that go from the ceiling to the floor. Hope this helps!

Open the blinds and close the waste basket maybe?

Paint in the walls, new round rug, wall art.

What style is the rest of the main floor?

I would suggest a roman shade on the window to bring some color in. If you want something more neutral, use a woven wood shade.

Simpler fan style....

Is this a rental or are able to paint etc? The first thing that popped out to me was the clock. Looks out of place on the wall...or at least too high. What does the rest of the space look like?
