This LoRA transforms the entire scene into a toy-like setting. Everything from outdoor scenes to plastic interiors. Colors are bright and vibrant and outdoor scenes tend to be sunny with blue skies in daytime or bright with stars and bokeh at night. It was trained on multiple types of toys from simplistic to more realistic.

Use the trigger n0vuschr0ma style for best results. I didn't include "plastic toy" in my prompts in the example images, but experiment and see what works best for you.
