Nice start. Dandelo has some very nice sand shaders on his site. Find a thread of his. The site is on the bottom of his replies. Martin has a lot of cool Terragen 2 stuff there.
And I love ancient Egypt!
If you worked on the sand, Bastien, and maybe subdivided the boat model in Poseray once, you'd be onto an even better render. :)
The water looks real and is superb...the rest displays a strong touch of surrealism....I like it!
