I don't think so but, I'm not sure. This is from one of the first mini-art books ever released which is sadly one of the only pieces of Azu promo material I haven't been able to find in good quality. Which is a shame because it has A BUNCH of stuff like this. About 43 pages including OP storyboards. I tried to get a guy I met to scan it but, he's been offline for years. This pic is just from the archive.
