Trigger Prompt: With focus on the subject and convert this polished art into a loose, expressive sketch. Emphasize raw, with many hurried pencil thin visible construction guides, cross-hatching, and subtle eraser marks. The feeling of an artist's initial concept, slightly chaotic and full of movement. Make sure to add messy, rough sketch lines to add flow and sense of organic draw, with graphite pencil on textured paper, as unfinished details, convert the illustration to a sketch into a preliminary concept sketch. Lines are rough, loose, gestural, energetic, raw, unrefined, spontaneous, broken, fragmented, quick, tentative, flowing, dynamic, scribbled, choppy, dashed, visible construction lines. Shading looks smudged, hatched, cross-hatched, scribbled shading, light, faint, incomplete, textural. Quality is unfinished, preliminary, conceptual, exploratory, raw, imperfect, abstract (if desired), expressive, immediate, spontaneous.
