Jassar has won the 3rd prize in CGArena's Winter Challenge. The mission was to create an image that gives you 'the feeling of winter', and I think Jassar did a great job. Congratulations!
There seems to be a bit of a trend that contest winners write a nice, long tutorial about their entry. Jassar is no exception. His tutorial focuses on the process of creating the image and not on the specific Blender functions that he used, but I think you'll find it an interesting read.
