Retrato a lápiz de una chica acorazada con mirada directa y serena

Pencil drawing on white paper, highly detailed graphite sketch of a slender young woman seen from the front, upper body portrait. She has long flowing hair and a calm, neutral expression with a direct gaze toward the viewer. She wears a form-fitting futuristic corset-like armor with intricate panel lines and three prominent circular emblems on the chest, paired with a short flared skirt with delicate fabric folds. The armor has a sleek, biomechanical design suggesting layered metallic plating. Clean precise linework with varied line weight — thick outlines for the silhouette, fine cross-hatching and tonal shading for depth and volume. Soft frontal lighting with subtle metallic reflections on the armor elements. Centered composition on a plain white background with generous negative space. Monochrome grayscale, high contrast. Style inspired by manga character design and sci-fi concept art fashion illustration. Calm, contemplative, mysterious mood.
