Messin' around with color again...

I think the dunes are pretty cool. The quality of the light reflecting from them makes me think that the material is angular and gritty, more like beach sand than the round blueberries in the area. They sort of "glitter" ("specular reflection" is the jargon term) and reflect light very differently depending on angle.
That little whatsit in the foreground's kind of interesting, isn't it? (The detail is 100%.) Something that fell off the lander, maybe?
