Thanks for the comments. My biggest compaint was that there was no feeling of depth. The opening in the cliff would easily let me show a deeper composition. I did not use any displacement mapping but manipulated the material mix percentages until it came out right. I also did a huge amount of detail work with the effects brush using mostly cracks and grit. I have never tried to manipulate a terrain to that dgree with the brush but have been pleased with the results. mokba
