Another image of mine that sort of developed of its own accord. Originally it was an experiment to make the nebula visible from the planet (I'd had troble in the past where the atmosphere made the nebula break up and look very grainy). As a result, the landscape is very basic (just a power fractal and a twist & shear with lean factor 2) and some fake stones to add a bit of interest. The light in the overhang was initially just temporary and to see what the texture of the rock looked like, but I actually liked the effect a lot so I left it in.
As always, very grateful for your comments.
Note: the banding in the sky is due to the jpeg conversion I think.
