Is it possible to add some shrubbery to hills and mountains? I think aesthetically those tiles would look more natural and appealing if the mountains had some shrubbery or trees on them vs. looking like a pyroclastic flow wiped out all life.
Other than that wish about hills and mountains I think it looks cool.
[Edit] Just noticed that is a volcano!, lol.
Anyway, if a hill or mountain is not a volcano can it have some foliage?
