Hi Bob, I also like the angle and the framing of the comp. I also thought the image had a color caste and removed it using Nik Color Efex "remove color caste". I also selected the stream and applied S/H to give the water a bit more detail. I also removed the blurry leaf on top and desat the greens a bit.
Hi Bob,
Agree with the advice given above and Dave's re-post takes the cast away. I really like the way you composed .....wrapping the main rock with the other larger boulders and keeping it all a bit off center. Very nicely done....just needs some tweaking like Dave's version.
