escape in collapse building

I'm a fan of Ultra Heroines and wanted to create an image of a room collapsing due to a monster attack, with people desperately trying to escape amidst the sounds of footsteps and destruction. I tried using Stable Diffusion but couldn't get the image with flying debris I envisioned, so I've created Lora. It's set to depict a school in total collapse, but the place can change depending on a different Lora (character) used, as seen in tests. Indeed, with Asuna, it tends to be a wooden building room, and with Takina, a wooden café-like setting. Therefore, if the prompt doesn't specify a location, the image will show the associated place in ruins. If a specific location is desired, adjusting the prompt should suffice.
