There was also one artwork of Cindy and behind her was I think a factory or a workshop, but I think there was also a plane and an aircraft hangar.
Also one about Lestallum.
Damn, now where I think about these artworks, I regret that I didn't took photos xD
BTW the one artwork with aerial fight next to a skyscaper this thing was a monster with red, yellow wings and a beak.
Hope this is also in the final game
