Hmm...I like what you have there already!

the clock is too big and the wedding frame is too personal for the public space. I'd move that table and mirror from the other room.

How about changing the table scape with the seasons? Bright beautiful art instead of wedding picture and who wants to know the time when they are eating? Floating shelves or three prints would look great.

I love accessorizing with large, interesting bowls on a dining table (and coffee table table).

I would add softer art to better suit rug and create more interest vs the clock (it’s also too large on that wall).

If it were me, I’d add one long rod across the windows, with added drapery for a more finished look.

I think your home and current tablescape is lovely!!

Lol...as usual, Houzzers have completely re-designed OP's space and thrown out all her furniture and decor. (although I completely agree about the clock and personal photos).

The topic is tablescapes. The blue-and-white scheme needs some warmth. A dark table looks good with white and lots of crystal and candlelight. I tend to go for the glam...

Oh, and orchids go with everything!
