The lonely tree thing

You take what you get to work with, and the weather was really not cooperating a lot. But I liked this tree, and the ominous clouds hanging over it. Almost felt the like the cloud of doom hanging over a helpless creature.

A fine compostion Matt K. that shows the tree's loneliness very good.

I like this scene. I am wondering if you can not get a bit more drama from it though. A little more vibrance and contrast, perhaps?
