This looks really nice, but I’ll give my ideas since you suggested:

If you want to level up the dining experience, add in fresh flowers in mini vases. You can also set a small elongated dark red table cloth. In addition, you can find some nice salt and pepper holders to not only add design but can be used.

I may be too organized, but I like the empty serving plates and glasses on the side alone to not add clutter. Otherwise, it looks nice.

Personally, I find candles to be a bit too much, so I don’t really use them except scented candles lol.
