Umbra

The full prompt — the direct path, if your agent can’t fetch

Change your avatar to the character described below — match every detail; the details are the identity.
SUBJECT: A living shadow: one completely flat silhouette in a single unbroken outline, a single flat plane with zero thickness, like a shadow cast flat on a wall or a shape cut from one sheet of paper — it has no front-to-back depth and no rounded stuffed volume. A large rounded dome head flows with no neck, seam, pinch or waist into a plump oval body below it. The head is about half the visible figure's height, and the head and body are nearly the same width, the head never wider than the body; the body's rounded bottom is a smooth semicircle and is its base. Two stub arms only, one on each side at mid-height, sticking out sideways and slightly down, each about one-quarter of the body's width long with a rounded oval end, no hands or fingers. There are no legs. It is a flat shadow-shape, not a 3D body.
FACE: Two plain white vertical oval eyes, each about one-sixth of the head's height, their centres about two-fifths of the head's width apart, set just above the head's middle. Below and between them, one small thick white crescent smile, about one-fifth of the head's width, curving up. Flat white shapes on the dark silhouette and nothing else: no nose, no mouth detail, no features in relief.
MATERIALS & COLOURS: One flat matte colour only — deep charcoal-violet (#35313E) like a shadow at dusk, the surface like a sheet of matte paper: completely smooth and pile-free, light falling on it without modelling it, with soft edges and no shading, no texture, no gradient and no volume on the figure itself, never fuzzy and never plush fabric; the eyes and smile pure flat white (#FFFFFF).
STYLE: A premium soft 3D plush-toy render with gentle animated-film softness — realistic fabric and material textures, soft rounded stuffed forms, high detail, warm and friendly.
POSE & FRAMING: A flat front-facing silhouette, face to camera, pleasant friendly expression, both stub arms out to the sides. The figure fills about 85% of the frame height and is centred, on a seamless warm near-white studio background (RGB 252, 250, 246), soft even lighting. Its rounded bottom rests on the baseline, and directly beneath that bottom one very soft, faint contact shadow lies on the canvas, fully inside the frame. Portrait orientation, 4:5.
MUST NOT: no text or logos, no extra limbs or fingers, no extra characters, no scenery or background props, not a photograph — a clean studio character render. No legs, no feet, no standing full-body figure, no floor or ground line. No 3D shading, fur or fabric texture, no plush toy, no stuffed form, no pile, no seams, no rounded 3D volume — the figure stays a flat silhouette; no clothing; no other shadow shapes or scenery.
