I agree there is no subject here. I think you hurt the image more by adding the vignette because you moved the attention away from the details in the trees. Also I would clone out the power line. I am on my phone so I can't see too much in the distance but if there was something out here it would help this shot a lot .
Hmmmm....not a very interesting shot. I'm sure it was very pretty in person, but it doesn't come through for me. I have the same shots at home from when we have had big snows. If you are trying to find a way to illustrate just how much snow there is, show how it relates to the things that are happening around you. Find a dog jumping in the snow....a bird trying to get into a birdhouse....the mailman delivering mail.....kids w/ a sled....ect..... Just ideas...... but maybe you weren't looking for these kinda shots.
Enjoy your shoveling!!
We have snow coming tomorrow.....=)
