This is one of my favorite Houzz console table with mirror looks. It could work for you;)

I'd start with a medium sized lamp, placed on the right. Bring a few home to try. That might help you decide whether or not the mirror is too small or if there even should be a mirror there (what is its purpose?). You might decide that artwork is better (I could see a pair of pictures, hung vertically in the middle). Once you have the foundational pieces in place, then you can add some accessories, such as a decorative box for the left side of the console, and books/plant/etc. on the bottom shelf. Good luck!

I'd raise that mirror a few inches if you keep it. Maybe a pair of candle sconces? Then I'd put something organic /shaped in the table. Could be a live plant, silk plant, or something involving birch logs or even fruit shapes (A little random, but I've seen interesting glass ones). To me the organic balances the geometry you've got going on.

I love that console table. Almost bought it myself earlier this year. Sconces would be aweosme but can be expensive to install. I'd do a glam lamp and something organic, like a small plant or flower.
