I really like the contrast you've created with the lush foliage and the factory it self. It makes me wonder what the story is. Is the factory abandoned and being reclaimed? Is is a secret industrial complex that needs to hide? Is it an outpost on a new planet that has explosive plant growth and it is a constant battle between the people of the factory and the vegetation of this place? There is so much story possibility here. I adore this! This is wonderful!
