Galaxy paint is a versatile LoRA that works with a variety of styles. The "pure" version without modifiers creates highly stylized illustrations with galaxy-like backgrounds, a primarily purple color scheme, and often adds florals and leaves.
It adapts easily to other mediums in your prompt while retaining the galaxy-like textures and colors. For example, photographs often have a purple matte look with the galaxy pattern in the background and on surfaces.
This style is based on artwork I originally created in Procreate.
I recommend experimenting with different styles and turning the strength up or down to your taste.
