Thanks.

The snow is indeed the weak point - i played with the idea of a 
subsurface scattering version but this scene is not fast enough and the 
geometry is not that good to show the scattering anyway.

The problem i have with the skylight macro is that it does not offer 
much control over the colors.  I used a different light color for the 
sky than for the light source to have more freedom in that part.

Another thing is of course that the use of a mesh for the sky is 
certainly not the best solution - although it is of course the only 
viable one with standard POV. A feature to have image_maps based on an 
internal array (or an ascii hdr file format) would be useful for this.
