I would take out all of the random things sitting on the floor except the table. Take off most of the things on the table. Get a mirror that is less bulky. Buy a more interesting rug that coordinates with your adjacent room decor.

What are your favorite objects in the space? Keeping those and removing the rest would be good to try.

IMO there are too many things. I'd remove the things in the corners, the pedestal and the things on the console. Keep only what you love for the console. Too many little things on it. Much larger art on the wall on the right. I can't tell what is on the pedestal but it looks interesting. Maybe that in one of the corners without the pedestal.

Agree with the others - fewer things and keep what’s larger in scale (bc of the tall ceilings)

Thank you all! the hall is longer than it looks in the picture. maybe i can show a different angle.

Anna, the wall you asked about is approximately 14 1/2 feet long by 12 feet 4 in high

One rug, wider and longer with more color. Mirror doesn’t go with the table. Random picture opposite mirror is not tied to anything. Remove stuff in all corners.
