The tree has some very nice fluid positioning to it- a nice sign of its struggle to live. The deep greens really bright forth the idea of this being a rich location, the browns strength, and the sunlight over the background peaks adds that beckoning out the beauty of the rest of the valley. This could use a little more coloration- flowers, etc- as well as variance; an indication of a river/water source would also be nice. The sun should project just a bit more strongly as well, and the bark should be a bit more defined.
