I can't help myself but I don't like mountains at all. I think you could give them more of your time. If you are just beginning with noggit - nvm, it looks good and you will improve in time. You can check for instance this, it may give you idea how your "sharp" mountain could +- look like:
I use:
rise/lower linear tool with around 4,5 radius and around 3 speed (for creating peaks or preparing for creating cliff)
flatten/blur flat tool with around 4,5 radius and around 4 speed (flatten for cliffs, blur only rarely or finished cliffs)
texture paint with around 2,0 radius and around 0,3 pressure
Not entirely professional-like, I could have at least 2 steps of texturing those rocky sides with different opacities and even lower radius to make them look a little bit better but I'm too lazy for that and don't have enough time for such things usually. So this is swift and quite OK looking, and also simple. Try to do something like that and find and polish your own style
. Good luck with that. And once again, if this is 1st/2nd project of yours with this size, good job, keep it up.
