Thanks, bkh !

It's a purely esthetic choice to break a bit the flatness of the top sails.
Well, I didn't defined exactly how things works. The air elementals are more or less supposed to push the sails and the whole ship up in the air, plus probably participate to the directional moves (with the side sails, notably).
Anyway, I spent to much time on this model already, so...

On a different matter, here are some hand drawn tests about mountains & a new possible avatar/logo.
