I agree, it really does look great as it is. Nice style. Love the mirror and console.

But I understand sometimes you just want something new. You could try adding a lumbar pillow to chair, maybe in a striking color, in a velvet fabric. Maybe a deep plum/eggplant or even purple.

I think it looks very good but seems the mirror is a little heavy looking for the nice table under it. I see you have an outlet there, how about putting a lamp where the plant is and the plant closer to the window side. A lamp may help the heaviness of the mirror. Also you might want to put your chair flat to the wall beside the table....catty-cornered IMO is not the best. A colorful rug would be nice but not necessary.

sky's the limit. what do you want? I'd do a nice little rug or runner.

And I might paint your door a darker color (Kendall Charcoal) and remove the mini blind.

some other options

Your dining room looks more modern so I would update to coordinate with that look. Brb

Probably a chunkier wooden console table and a good sized rug will make a more impressive introduction to your home

Played with some ideas for you. What style do you like?

Just to add ...the wood table to match the wood frame on the art..in color and rustic feel
