Attached is a new version, updated to take into account various comments. In
particular:
1) an area lights is used now,
2) the sea has been replaced by grass disappearing in a fog, and
3) the moment now casts a shadow on the grass (this works better now in
combination with the above two changes)

The lack of blue gives it an entirely different feel and I quite like the
result. Also nice is that the image is now quite different from other images I
have made, as many featured a lot of blue (water, skies, blue tiles, etc). So
thanks to all who have provided comments. Of course, feedback is still
appreciated on this image as well. :-)

Unfortunately, rendering time has exploded. It used to take less than two
minutes to render the scene without anti-aliasing at 600x800. That has now
become 25 minutes. This is even though area lights are adaptive, and the media
is very basic (fixed density and intervals set to 1). It is because the grass,
fog and area lights are each relatively expensive to render, and the combination
especially so. At the moment, the area lights have no added value inside the fog
(as there are no significant shadows there). However, I do not know yet of a
good way to exploit this to speed up rendering time. :-(

Cheers,
Erwin
