The issue of the craters not casting shadows is just that: if the object was
using actual displaced geometry you would see shadows cast across the basins on
the craters. But all you get on a simple bump-mapped sphere is shading... No
displacement of geometry, no shadows. It's not really a big issue at smaller
resolutions, but I think it is noticeable.

The other features I was talking about are something else. I'll highlight them
in a reply to Thomas.
