Haha, I LOVE photoshop - always fun to play around with pictures!
I was going to post and say that I definitely like the first picture better but I think that's pretty much the consensus already
I will say that I like the untouched version better - I think its more artistic and lends to the barrenness of the photo - the touched up version (while nice) seems like a hundred other photos that exist out there. The bleakness of the shadows and darkness of the tress in contrast with the vivid white of the snow is really startling and much more expressive than the photoshoped version.....
just my two cents......
