The trees should have leafs of different
color to make it look more detailed.

I think a complete different look is not
easy but you are doing it with a promising
strategy: emphasizing different parts
of the objects,
e.g. the door of your new house style
is much more emphasized than the house
roof which has been the main part of the
zelda houses, so it is making your new house
look more unique
