Desert retreat

I love this image. The tonal gradation's so subtle. I just wish it was higher res. Is this v-ray or mental?

There's a couple great tutorials on sand that just landed at http://www.ronenbekerman.com/

take good shape for the stones and a very nice mapping, small cactus on ground looks not realistic, no problem with the structure its nice.

Nice try. I don't like foreground tree and stones because look too fake.
