This LORA is a style for background.

Dystopian Ruined Hall, large abandoned industrial hall interior, wide empty space, collapsed wooden roof structure with a large circular hole exposing cloudy grey sky, broken rafters and decayed timber beams hanging inward, shattered roof framing the skylight opening, damaged ceiling trusses, ruined stage platform at the far end of the hall, cracked concrete floor covered with rubble, dust, bricks and debris, rusty oil drum on the ground, wet patches and puddles reflecting dim daylight, tall dirty industrial windows along the right wall, cold diffused overcast light entering the hall, arched doorway on the left wall, dark semi-circular arch exit leading to a ruined city, worn plaster walls with stains and graffiti, abandoned post-apocalyptic architecture, desaturated colors, natural ambient light, cinematic wide interior scene, heavy decay and long-term abandonment.

I created 15 datasets images with AI (DAL-E) based on my own prompt. LORA was created with fluxgym (RTX-4090).
