Blue Ballpoint Portrait Artwork

Use the uploaded image strictly as a visual reference for facial structure, proportions, hairstyle flow, and expression. Preserve the realism and identity cues while translating them into an illustrative style. Create a highly detailed portrait rendered in a monochromatic blue ballpoint pen drawing style. The artwork should feature intricate, swirling, thread-like pen lines, especially in the hair, where dense, flowing, chaotic strokes partially overlap and interact with the face. The linework should feel organic and expressive yet precisely controlled, with no randomness. Facial features must remain realistic and well-defined, smoothly emerging from the dense linework through subtle variations in pen pressure and line density. Use only deep indigo / blue ink tones, no other colors. Background must be clean white, untouched, allowing strong contrast with the blue ink. Create depth and volume using cross-hatching, layered strokes, and natural gradients formed only by line density, not shading or color fills. Overall look: elegant, hand-drawn, fine-art ballpoint illustration, contemporary yet timeless. Aspect ratio: 4:5 (vertical portrait) No text, no borders, no extra elements.
