I like 1 and 3 the best and I believe 3 is the strongest. I am curious what 3 would look with the tree trunks on left and right cropped out. Don't get me wrong, the trees left and right provide a nice balance, but I wonder if they detract from the scene.
These are just amazing. I've seen similar drawing or painting in story books but I had no idea such a magical place actually existed. I would be printing #1 & 3 HUGE!
