i wonder if you're working with a monitor that is too dark or something, because the black inside the cave is just gray. The lack of rich blacks inside the cave and on the rock outside really hurts what is otherwise an excellent photo. If it's not supposed to be pitch black, there should be some detail to see. Still a great photo that could be fixed up in photoshop. 7
This focus here feels too soft, and the low-contrast toning is not effective for me. It's also one of those images where I scream a bit for a more definitive focus object (what you'd want me to focus on when I look at the image).
