Then I found the hi-res version using reverse image search (Yandex found the posted version):
The plane and the tank look like they’re from Nausicaä.
Miyazaki’s watercolours are always great.
Was going to say it looks like Nausicaä, I’ve got the manga books, beautiful images and fantastic story. He does female protagonists really well
There’s also a giant artbook with an the watercolours he did for the manga that I can really recommend.
Nice, I’ll check it out
