Mirror looks much better this way. Rather than a console table under the mirror (because I know you already have that set up in your front hall) - I would place a simple white or muted print fabric upholstered bench under the mirror. It's great place for guests (or your family) to sit and put your foot ware on.

Below are some pics for inspiration:

Pic 1: Simple bench with arms with a muted pattern.
Pic 2: A more ornate bench with some "weight" to it (for grounding the space).
Pic 3: A lovely simple bench with arms - can be white or a darker shade than wall with a white cushion in one corner.
Pic 4: A heavier look with storage for shoes, boots, scarves etc.

What ever you select it must be a good balance with the "weight" of your mirror. I personally like the benches with side arms - they better define the space add weight without taking up a lot of room and you can layer it with a cushion and throw to make it more interesting.
