transform this 2d architectural elevation into a loose artistic black and white sketch with expressive shadowing maintain accurate proportions but reinterpret the linework with a hand drawn feel use a soft light source from the upper left introduce organic slightly imperfect line variation to mimic pen or pencil sketching apply shadow using loose cross hatching light scribble shading and varied line density rather than precise drafting techniques emphasize depth by layering sketchy shadows under roof overhangs eaves porch ffits window recesses and balconies use darker denser strokes in deeper recesses and lighter more open strokes on exposed surfaces suggest material differences siding stone roofing through texture rather than tone use varied hatching styles broken lines and subtle pattern shifts avoid solid fills and keep everything strictly black and white allow slight abstraction and artistic looseness lines can overlap taper and fade naturally the final result should feel like an architect s conceptual pen and ink elevation sketch with depth movement and character
