Need some terrain help

[Ironside]

Hello, I'm making a Warcraft III Worms 3D map. And as you might know, Worms uses a lot of different terrains (Some are desert, some snowy lands, some forests, some cities, ...) So I'd like if someone can suggest me the best possible custom tileset.

If you need some more information about the map, it's here: https://www.hiveworkshop.com/forums/map-development-202/warcraft3-worms-3d-156815/
