Thanks, and yes, I know some things are really awful, like the sheep. In the meantime I've added some huge rocks (fake stones of 1k) on hilltops, added Daniils erosion shader only for mountains a bit further than the heathered area (I didn't want to mess with that), masked snow by altitude (and smoothed that snowy terrain part 50%) and added the flowmask for some lower unsmoothed 'streams' of snow (which probably isn't very natural), and made some fur on the sheep (so now they're Jacobsheep), and redistributed them.
Also added some displacement to rock/cliffs after eroding.
