bonsai design

hii everyone , i have this ficus that i cut back hard and there is a beautiful base and i wanna make a shohin to medium size bonsai . I am planning on a banyan style bonsai but i have no idea on how to develop bones and branches . does anyone have any idea on how should i approach this tree ?

Basically I'd love to look into how different nations/cultures do bonsai as I've heard like all art bonsai is no different with its cultural influences. I'd love to find out the names/be pointed in the right direction to photos and examples of these as I've heard Spain has a different look...
