Esquisse technique de design de la Mini Cooper vintage

Hand-drawn concept art sketch of a classic Mini Cooper (vintage model) shown in a technical design sheet style. The car has a vibrant yellow body with a contrasting matte black hood. Rendered on textured cream paper, combining rough cross-hatched shading with precise blueprint-style linework. Surround the car with detailed handwritten annotations, arrows, and engineering notes such as "MK1 grille," "chassis datum 0-0," "wheel offset," and "torque spec: 90 Nm." Include measurement markings and construction lines to enhance the industrial design feel. At the bottom of the page, add smaller inset mechanical diagrams showing suspension link geometry and brake calipers, with selective neon red highlights on key components. Style should feel like an engineer's notebook or restoration blueprint - highly detailed, slightly messy, but intentional. Lighting is soft and neutral, with subtle paper shadows and natural sketch imperfections. Color palette: limited - cream background, bold primary car color, black accents, and minimal neon red technical highlights. Mood: industrial, vintage automotive design, precision meets artistry. Optional Add-ons (for customization): - Hyper detail: "ultra-detailed, 8k, sharp focus" - More vintage feel: "aged paper texture, slight stains, pencil smudges" - More technical: "dense engineering schematics, exploded view elements" - More artistic: "loose sketch lines, expressive ink strokes" - Camera angle: "3/4 front view" or "side elevation technical view"
