This is a versatile outlined illustration style. It typically has uncolored forms, hatch-style shading, and lots of negative space. It has a bit of a sketchy look but can be quite detailed.
The trigger is "n0vuschr0ma style" but you can also add specific styles to the prompt to change how the style looks: coloring book page, pen drawing, sketch, line art, logo, colorful outlines, and so on.
