Nice setup. I like the melt (and the chunks of snow on the slopes) the best, but with a little extra effort.....
The dark crack-like texture on the slopes; is that due to displacement intersection with changed settings? (I have the idea I recognize that strange color). I think it's better to 'leave that out'. Then I think you need to use some bluer colors on old ice, to give it some more diversity. Maybe keep the tops rocky?
