Not a suggestion, a question.  Such as how are you going to get that station
to sit on such a slope?  Going to be partially built in?
The white seems a little on the over saturated side, maybe toning it down
some would be better.  Looks like you used noise3d on that ridged
multifractal for the overhangs there.  I tried some that way but it takes a
while to get them to where no parts are suspended in mid air.

I like the first one, looks a bit like one of those ancient paintings of arctic
expeditions.  

The crystals seem a bit too transparent to me, but maybe they just suffer from
the lack of a background to reflect. They don't look like ice crystals so they
probably won't fit in the landscape.  

In the third one i do not realize the difficulty (the stats seem quite extreme
though) but maybe i just don't see enough details in the pict.

Crystals look very nice. Can you change the texture/interior?
They'd be nice for amythest crystals, the ones sometimes found in the
center of rocks.

Now this is what I'd expenct an ice planet to look like.

The render time isn't bad, but I don't like disk thrashing.

Yes! That green post should also be out a little farther than it is, but that's
just a mental note, no need to make a whole nother render.

Nope, all RMF. Perhaps I didn't use the correct setup. I like the overhang
though, it serves as a natural shelter for the outpost. I agree the snow is a
little saturated, it's just hard to get it to look right on a monitor because
they're so dim compared to real blinding glare...

Thankies!

Well, the render time for the outpost is more than the crystal, landscape
and vehicle put together (though it was at a higher resolution). I can
possibly make it a little smaller in mem, but not much. :-(

But of course.

Methinks so too.

Oops, forgot reflection! The crystals I was just toying around with, they need a
little work.

It's fairly simple in theory: for each layer of bricks, make a grid, and specify
each element as outside, part of a cylinder, or part of a hemisphere. Next, go and
take out any "nubs" (cylinder elements that only have one adjacent cylinder
element). Then go laying bricks around the outside of the cylinder portions. Then
fill in the domes (the domes are solid :-(  ).

Personally, though, I find POV-Ray's language hard to read. I am used to C; you
always know where a line ends with a semicolon, no manually incrementing loops,
'{}' indicates blocks rather than objects.
POV, on the other hand, is very dense visually; characters like '#', long keywords,
etc. Loops and other control aids are virtually indistinguishable without actually
reading the code, because in order to change a variable you need #local or
#declare, which has the same first character and is the same color as #while and
#end.

Of course, that's no excuse for '<' versus '<=' or indexing from one... ;-)

As has been mentioned, they would make great quartz crystals...are you 
going to post the source?
For ice, maybe thinner, more needle-like crystals would help.

Completely solid? Ouch...maybe you should leave out parts in the center. 
It would parse a bit longer, but would use less memory.

I agree...I think it would be an improvement to use {} blocks for while 
loops and other blocks. Or at least have different ending keywords: 
#endif, #endwhile, etc.
And another thing, it is often difficult to tell if a piece of code is 
creating a variable or modifying it. I have proposed a #set directive 
that is incapable of creating a new variable but would be used to modify 
existing ones, but I seem to be the only person who thinks it is a good 
idea. :-(

I like the largest and the smallest of the domes.

Have you tried to let the height of the poles (plates ?)
be slightly random ?
