BTW, I really like how the ground turned out too. I used a picture of cracked ground found at www.imageafter.com and edited out the out-of-scale stuff (grass, etc.) using clone stamp and paint tools. Then I separated out the cracks (dark) and little brush debris (light) into two layers so that I could amp them up while toning down the background texture. All of the little scrub and bone-like bits are painted into separate layers using sampled brushes that I got from a covermount disc in an issue of ImagineFX - $17 magazine on fantasy painting, but worth every penny.
