This LORA is a style for background.

Dystopian Overgrown Hall, a vast abandoned industrial auditorium is enclosed by cracked concrete walls, exposed steel roof framing, and rows of tall rectangular factory windows along the right side. In the foreground, broken floor slabs, scattered debris, shallow standing water, and dense vegetation spread toward the center. A broad raised stage occupies the middle ground against the rear wall, its straight concrete front edge covered with moss and plants. On both the left and right sides, separate narrow stairways with metal handrails rise from the lower floor and connect directly to the elevated stage. Above, a large collapsed section of the roof opens to daylight, with fractured beams, hanging panels, cables, and long trailing vines descending into the hall. Sunlight enters through the roof opening and right windows, illuminating grasses, ferns, climbing plants, damp concrete surfaces, and reflective puddles across the ruined interior.

I created datasets images with AI (ChatGTP) based on my own prompt. LORA was created with fluxgym (RTX-4090).
