I agree, the mirror looks too small in the center...move it to one side and put artwork on the other side. This will balance the mirror size.

The top of a lampshade should reach about halfway up the mirror.

If you're going to keep the mirror, I might do two lamps on either side, or one lamp and a large jug. Example:

Take a look at a Mark Sikes design book. He's all about the blue chinoiserie.

My first thought was the same as Sabrina’s…two lamps might help the balance with that mirror.

I have ordered two lamps to see how they will look on each side of the mirror.

The mirror you are using looks too small to work well over the console table, unless you want to flank the mirror with sconces and forgo the lamps. Perhaps look at a larger mirror or some artwork instead. Here are a few pictures of designs we have done in entryways and bar areas:

If keeping the console table, we might suggest getting a different mirror, or large piece of artwork, to go over it. Here we have some of the entryway designs we have done for clients:
