An anime life simulation with space, music and RPG elements? How weird! This is the proposal of the this project, made by a single passioned girl gamer and aiming to deliver an unique, cross-genre experience.
I gathered the data from the brazilian votation also, right now some interesting patterns can already be seen. If you hadn't voted, the votation is being held at the game current news article. Comments would go well to complement your vote.
Remember, once I make these characters in 3D there will be no turning back.
I can only speak for myself, but the reasons I liked the lion centaur not as much as the fire boy and the fortune teller were:
a) He was "posing" instead of doing something else, so I couldn't imagine him in his normal environment. The boy and the fortuneteller were occupied with something, which immediately added to their information(/character depth).
b) The device on the lion centaur's left side looks cool on its own, but rather out of place with this character. All three Solarians are giving me traditional oriental vibes (especially the fortune teller, she seems to be inspired by India), and this weapon(?) is the only thing that doesn't fit into that picture. Maybe if it had another form, it'd blend in more easily - but even then, I'd expect it to be carried by a more frail character, and the centaur to be carrying something heavier.
I do think you had come to some interesting conclusions, I will implement them on the revision art for the spider girl and lion centaur. You're also right about the "oriental vibes", I'm using as reference that region associated with hot climate and deserts.
Thanks. Keep in mind though that I'm just one guy and my opinion is not representative of the others (e.g. I prefer Solarians, while others might prefer Nightkins). Experimenting is always good for the game.
Don' worry, if I agree with an observation it is because it do makes sense.
