Ok, so this needs to be used as a reference for actual modelers to be able to sink there teeth into.
This is not abstract, not a generic picture of particles that fill up the screen.
Think about what a blight storm might look like on the Red Mountain from a distance. Think what would it look like inside it. And remember that these will be physical models, so needs to be specific.
Same with the Ash storms, these come in at you from a distance, foreboding.
A very very hard challenge indeed as its a specific reference for modelers.
