I've tried to get an idea of how big the region is. I think it looks a bit big, any of the areas that could be left out maybe (and maybe become another region later)?
Even though I know some of the old regions are bigger, I think it'd be a good idea to have future regions not vary hugely in size, generally 100,000 to 400,000 sq. m.
Though I think it's good Akėnakii's borders have been taken into account in the proposal
