Blue Ballpoint Pen Woman Portrait Drawing Prompt

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, neck, and shoulders. The linework should feel organic and expressive yet precisely controlled, with no randomness. The subject’s head is slightly tilted upward, with the gaze directed off-camera to the left, conveying a calm, introspective expression. Head-and-shoulders framing, slightly including the upper chest and both shoulders (no outfit visible), with a centered composition and balanced negative space.
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, with 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)
