When I first saw the sandstalker, the saddle reminded me immediately of a camel's saddle. This, combined with the turtle-like Kardas head, led me to think: "What if the sandstalker was like, a turtle, but with, like, a camel's hump... For a shell. But huuuuuge."
Anyways, I really like how this turned out. The gradients turned out quite nice, though the one on the sand removed most of the texturing details I had. I also turned up the saturation and contrast a bit on the shell to make it look nice and scratched up. (Probably by sandstorms.) According to BS01, sandstalkers can go a long time with no sustenance, so the hump on this one is... Relatively canon.
