The mountains look a lot better.
That's what you get when you learn from people who really know how to draw - and I'm glad I didn't try to teach you my own relatively amateur way (which was to just keep scribbling till you get it looking better than it was! LOL!)
Regarding the ice blue mountain colour...
You may have a bit of trouble getting the mountains the right colour if you just plop straight for ice blue and don't think about why they are ice blue first. Are the mountains actually made of ice?
I don't know if they are ice or rock, so I can't say very much just yet about the colours, but I can suggest that you start with grey tones - shading the mountains first, and then using a separate layer to add colour once you have them looking pretty convincing as mountain shapes in grey. Even if they really are made of ice, start grey - just paler greys than if they are rock
Adding colour on a layer above (usually done in overlay mode) means that you don't destroy the perfect shading you've done underneath, and you have the freedom to scribble colours at will, knowing you can just scrap that particular colour layer if its really horrible and start a new one.
