Thank you very much, everyone. And thank you Designer for the nomination: it's nice to receive such a nod of recognition.
Derrel, this was a very long exposure and whilst I wanted to capture the full effect of the lighting in the well, I wasn't sure if I'd gone just a little too far. There are some blown/clipped whites, but I feel these lend the scene a certain edginess. Good to know it looks alright to such discerning eyes.
