Well, for one, you could lessen the Gain on the bump function(s), which will, in turn, lessen the intesity of the bumps. When I first saw this, I really wasn't inclined to complain about the sand though, since something else bothers me about this: The scale...Compared to the apparent scale of the surroundings, the girl looks huge, and I'm going by the density of the atmosphere (mostly), I think, to come to that conclusion. Maybe it is, actually, my eyes wanting to make her look out of scale due to the local surroundings' scale (the terrain),but I don't know. maybe of you added something else of a known size, it would help to set a scale.
