Amaterasu's wrecked Ship

Image made for a personal IP I'm working on, set in the XVII century in Japan with some Alien sci-fi Tech.
Tomoko is a fine inventor and an independent spirit of the Tokugawa period. She is passionate about inventions and relics from the past associated with the ancient Shinto gods.
Her knowledge quest leads her to this forbidden and holy place, a stranded alien structure that is believed to be one of the Kami celestial nests probably Amaterasu Space ship.

I'm testing out a new environment painting workflow, still have a lot to figure out to get to the result I want though.
