Maybe taller objects and more colorful? Repeat color in maybe a couple throw pillows across the room.

Hello!

You could add a book assortment on one side and a picture frame on the other! Just ideas!

-Cabinets and Designs

I would repeat the touch of greenery (as seen on coffee table) on the buffet.

Oh, I like Margo's idea! That might make the exiting items work out quite well - just placing the branch between!

It looks like you are going for an asymmetrical look. However, the heights of the lamp and taller candle are too similar for this to work. You need to replace one of the items with something taller/shorter for a more dramatic height difference. This example is more extreme height differences than you need, but helps make my point. The lamp is very tall, bowl very short.
Pulling more color from the artwork would also make it more interesting.
Good luck!

I agree with crowley48, layer in taller objects in front of the mirror and add an accent color that you repeat throughout the space. Greenery (as others suggested) would be great and would add some height. Here's what I did in my last project (examples of layering various heights in front of the mirror).

So many suggestions involve things that are rather easy to try.....any got your interest? Anxious to see since that is a great space!
