A low-poly 3D character in a standard T-Pose. The character is a young girl, 8 years old, named 'Lyra'. She is sickly and pale, with faint dark circles under her eyes. She is dressed in oversized, tattered winter clothing: a large knitted beanie, a worn-out red coat that is too big for her, and mismatched gloves. Her facial expression is tired but gentle. The model should be optimized for Roblox, with clean geometry and simple textures. Render the model against a plain gray background.
