Great forms and nice view of the contextual environment. I'd perhaps like to see a slightly higher viewpoint with the camera much closer to the rocks. If shot with a tripod and longish exposure you could have achieved an amazing DOF which would have made this a stunner.
These are some pretty crazy rocks - are they fuzzy or is that moss on them? I think if you'd had some natural lighting on them - especially side lighting - the texture would be amazing.
I bow to you for trying to photograph this subject which is IMO one of the hardest to do. I like the composition, lighting could be better but the colours are rather dull. Perhaps some more sharpening and colour saturation would help?
Nice shot, I like it. The composition is great. Constructive criticism - the color overall looks very real, but there's nothing that really grabs your attention and says, "Look at me first!". Aside from that, I love it. Great job!
