if this ends up being a series of anime, movie and or a game, make sure the characters speak Japanese (this is *japan* of course), try to make it as true as possible and don't just slap english in there, i've seen countless of anime,movies and games that do that same mistake, it will just look like a "dub" version, which in itself is just as bad.
i love futuristic stuffs and sometimes i wonder why it takes so long to develop stuffs from the future, if we have the so called creativity which defines us from any other animal (yes i said, we are animals, the way we treat each other should be a good response) anyway make sure they speak Japanese, since the cover of the book in your page has Japanese words and not english. however the english can be used in a way that people know it's a translation.
Aaah, cool. Well the pics are cool anyway... i just like to know as much as possible about the things i like You really captured the spirit of neo Tokyo the way i see it. A mix of Ghost in the shell and Akira.. but more robust.
