Well they were suppose to look sureal but i cant get them to look covered with sand in a realistic way...
If you got any ideas how i can edit it nicely in the gimp im open for suggestions...i really wouldnt like to generate a texture again...
My suggestion: use bevels, at a 45-degree angle, and make various "layers" of hand-painted repeating rock textures, then hand-paint with the pattern-stamp to create areas of detail and weathering.
