What do you need? Do you need a thin console to place things or will it be simply for decor. A gallery wall with the mirror incorporated in the scheme would be ideal for the big wall. A very thin console under window, no mirror, would look grea.

I like the idea of a small shelf. A group of three on the wall might be nice. Here is it in your place and on a wall a little larger

A gallery on the long wall would be nice.

Is the mirror high enough to be useful? It looks much too low to me. I'd replace it with a very narrow shelf with some heft to it. A narrow live edge shelf like Blue showed would be really nice looking. Maybe something sculptural like a burl or branchy wood or driftwood on this order would be in line with the modern lines of the area. No lamp, but a small rustic ceramic bowl to catch small items and stuff like a hummingbird nest, weathered sea shell or group of small beach pebbles. A piece of reclaimed wood set as a floating shelf works as well. Be best if each end was good and weathered.

I find the mirror feels too low and once you have the opposite wall accessorized, I wouldn't add anything under the window. I think there is so much potential and go for impact using modern items that also feel warm.

CB2 has a great selection of narrow console tables that would fit your entry nicely. You could do the mill table on the blank wall side and the mini mill table on the side with the mirror http://www.cb2.com/mill-console-table/s172901

Artwork would look nice along the long side above the longer mill table flanked by two sconces. Here's one of our favorite modern sconces by Rejuvenation: http://www.rejuvenation.com/catalog/products/cedar-moss-sconce

Another way to warm up the entry is to put a runner down the hallway so visitors have a visual path to the rest of the home
