Winter Wonderland

I've struggled this evening to decide which picture to put up. 
Should it be the freezing fog that greeted me when I opened the bedroom curtains? Or the freezing sparrow hiding from the cold on our terrace? Or the bird feeder so frozen it wouldn't swing? Or the a=Japanese Acer, rimed in frost? Or the stunning umbelliferae down by the river?
