Maybe the ice became a little to green, but IMO, the greyish ice looked a bit
like overcast sky.  

I also added some smaller pieces of ice, but i don't like the way they look,
have to try something else.  

Furthermore I tried adding reflection to the ice texture, but the speed got very
slow (about 5 pps for the bottom part), so i did not use it for this render.

As usual comments are welcome, there is also a larger version available:

Really cold --- er, cool --- Pardon the pun.
It's just occured to me that there aren't any overhangs in the ice at all.
I thought it was also isosurface like the land, so any chance of getting it
to undercut in places using some form of the iso?
I think the greenish tinge compliments it well.  A couple of the near-left
chunks of ice seems to show the underwater part more than the others.  And
then there's that very different one nearly submerged...  not sure what to
think of that but I like it.  Can only dissect at this, it's a great scene.

When seeing it render, i thought it looks warmer than the old one (ice seems to
melt on this one, doesn't it ?)

Both mountain and ice are heightfields, so there can't be any overhangs.  I will
probably try some single floes in the foreground using isosurfaces sometime.

Thanks.

I use a bozo pattern to the higher parts of the ice heightfield, it's probably a
bit to strong.  

The one floe in the middle *is* submerged, except a small part on the near
side.  It would be probably better partly under water like the two ones on the
far left.  

The difference in the underwater parts is probably cause by the light coming
from the right.

No photos allowed... You can not fool me...
Really a wonderful work... =)

Q: The ice and mountain are two different HF's...?
Q: If so, How did you join them so seamlessly...?

And WOW ". (= applause from the peanut gallery =)

Thanks.

Yes, the ice is made with Povray and some code Rune posted some days ago little
modified, for the mountains i used a seperate program.

They just overlapp :-)

Wow!

These are getting to the stage now that instead of saying "such 
a thing looks realistic", I'm saying "how can I tell that this
is raytraced?" and there isn't anything in there that doesn't 
look real (apart from the too green ice but you know about that).

It'd be good to put a few different views of this on a web page
and title the page "my holiday in Antartica", you'd possibly
get people writing to compliment you on your photography.

I know many people that could be fooled.  None of them here though.
