Thanks, good points. The highlights are totally blown out, but maybe I can get some detail out of the shadows...
For your second point, the composition is maybe a little unbalanced, but I liked the rocks, lichen and fallen stump on the right, To the left there was nothing. I see what you mean, but I cant think of a way to fix it. To me it sits pretty ok, a sort of A shape.
I'll have a go at fixing the contrast though.
