Snow Anyone??

I snapped this photo on the first night of Atlanta's recent snow/ice storm. I used the automatic settings on my camera. I'm new to photography so I am just learning about focal lengths, f-stops, aperature size, etc...so of course the picture could have been much better. I opened my front door, stuck the camera out, and snapped the picture. Just wait until I really know what I'm doing. I welcome any suggestions as far as what I can do to improve the image in Photoshop or Lightroom. The picture has been deleted from my camera,
