Already there, but you do not see much of it.

I tried that and it did not change anything...

See my second version, I did not yet try media, but even without, it works quite
well.

That's exactly what i'm doing all the time :-) I also thought about smaller ice
pieces, would be not that difficult to add them, but I'm not sure whether they
would look good.

I meant removing some parts/selective changes.  For example i removed some part
of the mountain HF behind the camera casting shadows on the foreground.  Of
course you could have removed them from isosurface with CSG operations, but that
would be much more difficult.

I already considered that, it would need a different viewpoint/view direction
but I will give it a try...

Thanks for your suggestions, even though I'm not sure whether i will have time
to try everything in the next days ...
