I went with an android / cyborg girl, because Finland is considered a high-tech country and the map of Finland is known as "Suomi-neito", the Finnish Maiden. Also, the character should be quite small, because this is a small nation
I'll probably change the coat to a fur-lined winter coat for the Winter seasons, and keep the swimsuit-like underclothes to represent the lakes.
I should probably change the other arm to be more clearly detachable, to represent the changes in geography.
I'm also toying with the idea of using a Kantele, a traditional Finnish / Karelian instrument as a weapon, combined with the sword of Väinämöinen.
