Honestly, I say keep the buffet and the painting as placed - both are lovely and work well together! But I will suggest a quick edit. Remember: less is more. We want to highlight, not conflict with, the beautiful array of colors within the painting, so I would remove the red runner.

Plus, we want to softly guide the eye, ultimately focusing on the painting rather than bouncing from one symmetrically placed item to another. Removing the center plate and the cake stand will help create that. Keep the wine bottles as they are and opt for a basket or wooden bowl placed in the center of the table.

You'll achieve balance, not rigid symmetry, creating a harmonious table display for your dining area. Enjoy your space!
