I like the tall arrangement suggestion. Something colorful and tall enough to be reflected in the mirror.

Maybe switch it all up? I think the candlestick grouping would look nice on the buffet, placed where one of the silver jars is. Candles burning look so pretty reflected in mirrors.

If you want to keep it simple, just add one or two other items on the other side. I posted a few examples below, but I don’t know what your decor preferences are, so these are just very basic ideas.

Are you attached to the runners? If not, I’d get some lighter or colorful ones (and maybe just one for the dining table and not the buffet).

^^^ One jar, not three.

For the dining table, you could try arranging the buffet items, just the white bowl alone, or something completely different.

Thank you all these are excellent ideas!!!

I already switched everything and it already looks better, thank you!

Awesome! :)
