As so many have remarked, looks like a very familiar walk - definitely the stuff memories are made of. I wish their heads did not merge so much with the trees.
As others have said, nice placement of the group. The side lighting adds a lot by revealing the folds/creases in their clothing, which enables me to better "feel" their movement.
A family walk down a well trodden trail in the late afternoon light. The family stands out nicely against the dark trees. The snow, especially the snow that's in the sun, looks a little more grey than I suspect it does in real life.
Beautiful light and detail. This is just me, but I'd like to see the people and dog coming towards me. This is a good composition, but I'd like to see their faces.
