I started with a path through a dead forest. Added some stones and a powerful light source. The focal point was missing, so the alien-ufo came in. To add to the story, i added hints of a war against samurais. Finished with some composition and effects and done. Took about 3 hours to make.
Stones and Textures from Poliigon. Trees from vegetation.
