By altering the balance between the light and dark parts of the picture, it is indeed much better. I would still have problems with the composition in terms of its subject, but that is my taste, rather than an absolute technical kind of thing. But I tend to take pictures like this too, I see something and think "Brilliant! That's great", get the shot, but then on reflection realise that simple chunks of nature are not in themselves great pictures. The truth is we have to do more than just 'capture' the landscape or the world out there. We have to DO something to it - and I don't mean mess about with it for hours in Photoshop - we have to transform it with a personal vision somehow. Which may mean waiting days for the best light, or the perfect sky, or 'walking the shot' looking for better angles, or just plain being ready when something magic happens.
If I knew how to do it I'd be rich and famous and not messing about on LL Forum. So good luck to you, mate.
