Oooh, I like this. It's pictures like this that make me wish I lived outside of a city (my grandparents live near a river a bit like this one). This is going directly into my 'favorites'. :)
The way the skys white hue compliments the white of the snow on the trees, and the rivers hue compliments the greyish brown of the trees creates a nice tight shot that is quite pleasant on the senses.
