Thanks,glad you like it . And no,I haven't used some special trick or something...but it probably went out like this because : 1. I took he picture while in my car which was moving and the window was closed. This made it look sort of blue. 2. I edited it using photoshop cs4. Used a gradient map with blue,grey and white colours. This made it a little darker.
this is a fantastic piece of work - after looking at picture after picture of snow photos this one actually made me feel cold. however i would advise you to find where the shadows have turned purple (such as the top left near the trees) and turn it blue.
