Saw this the other day. Really interesting shape you've got there. Looking at, I can't make up my mind if it's slightly out of scale with the trees, or would be ruined by too much detail? It's almost as if I'd want to see similar angled cracks and bumps breaking up the cliff sides, without losing the overal grandness of the general shape. Definately some subtle instance of scree where you'd expect, just painted in to mask a slope constraint. I'm not sure if you'd want to see veg up there either. I quite like that it looks like a very dry piece of rock.
