The sky wasn't "working" to your advantage on that day, now was it?
It was bright but cloud covered, I assume ... but one can only assume since there is NOTHING left in your photo in the place of the sky. And that is what bugs me a bit.
Is your negative all black there? Nothing to be rescued in a different kind of developing process (thin ice for me here, I know next to nothing about darkroom work, so I better stay quiet and hide my total ignorance).
I'm not sure I am overly happy with your composition here, either, the horizon line looks quite centred to me. Pointing the camera down more to exclude more of that bland, non-descript sky, get better exposure readings for the ground and create a more pleasing composition might have helped.
Sorry to be so open in "just" Landscape and Nature, this is not Photo Critique in particular, but I feel like we should also speak our mind in the Gallery Forums, shouldn't we?
