Agree that the rug is too big. I think the rest is fine.

I like what you've started, but agree it would look better if there was at least a foot of exposed floor around the edges of the rug. Can you exchange it for the next size down?

I'd put in a console table with stools underneath. This would allow you to bring the mirror up and the size might be fine for the wall.

For context of the space.

Do you need the space to be functional or just pretty? or both? Is that the main entrance? Do you need a drop zone for keys, etc. I think I saw closet door across from the front door- is that coat storage?

I think a mirror 3X that size, or a nice large piece of art would be great there. A taller plant, or your plant on a stand, would be better, especially w/your tall ceiling.

this would look so much better w/an appropriate sized rug in a diff color

some other ideas, a throw and a vertical piece of art. similar size to this one.

if you get tired of a bench, do a small chest or console w/art
