Monochromatic Blue Ballpoint Pen Portrait

Use the uploaded image as the ONLY identity reference. The subject must match the same person with 100% facial accuracy — preserve exact facial structure, proportions, eye shape, nose, lips, jawline, and overall identity. Do not beautify, stylize, or alter facial features. Fix and refine the hairstyle only — keep the same length and type, but make it naturally arranged, clean, and well-defined (no messy or poorly generated hair). Create an ultra-detailed monochromatic {argument name="ink color" default="blue"} ballpoint pen (biro art) portrait that looks completely hand-drawn using a single blue ink pen. Use fine linework, smooth layering, hatching, and cross-hatching to achieve realistic depth and tonal variation. Composition & Pose: Full body visible. The woman is sitting on the floor beside a window, leaning slightly back against the wall for support. One knee drawn upward with arms gently resting over it, the other leg folded naturally along the floor. The pose should feel relaxed, natural, and slightly introspective. Head Direction & Expression (VERY IMPORTANT): She is looking outside the window (not at the camera). Expression is neutral to slightly emotional — deep in thought, introspective, calm, and quietly reflective. The image must strongly convey a “thinking moment” or inner emotion, not a posed portrait. Eyes (CRITICAL DETAIL): Eyes must be highly detailed even in side gaze — soft focus toward outside, subtle light reflection, clean eyelid structure. Expression should feel alive and emotionally connected to the scene. Clothing: Subject is wearing full lower-body clothing (e.g., {argument name="clothing" default="jeans"}), naturally folded with realistic fabric flow. Upper clothing is a light-colored top/sweater with soft, breathable texture (not heavy or bulky). Environment: Old-style {argument name="era" default="90s"} home interior (not modern). Window on the left positioned above floor level. Simple frame, slightly worn surfaces, vintage feel. Lighting & Shading: Strong natural light from the window (left side). Left side: soft highlights, near-white paper Right side: deep shadows with dense cross-hatching Smooth gradients, no blotchy ink Material Rendering: Hair: fine flowing pen strokes, natural volume Skin: ultra-smooth tonal blending Fabric: soft, light texture Hands & feet: natural relaxed anatomy Edge Treatment / Blending (IMPORTANT): Entire artwork softly fades into the paper from all sides. No hard borders. Style & Quality: Hyper-realistic, museum-quality biro illustration. Must look like real pen-on-paper, not digital. Framing: Vertical 4:5 aspect ratio, full-body composition, balanced with window visible. Output Tags: ultra detailed, photorealistic drawing, blue ink only, fine linework, smooth shading, soft fade edges, high precision
