I like this, though I think the whiteness of the sky is a bit too bright and harsh. The light on the rocks is very nice. A crop would fix it up nicely! :)
This is a very interesting subject. Unfortunately the sky is really really hot. Might've been a good candidate to crop and also a more creative corner to corner framing of this large rock would've worked for you.
Nice framing of the shot overall. The way the light washes out the upper part of it was distracting for me - maybe if you'd angled the camera a bit lower, lost the tops of the trees, it might have countered some of that, but I'm not sure it wouldn't have lowered the shot too much to work...was the light/look bad from the other side?
