Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright, figure centered with a dim forest filling the sides. The Doppelgänger is an unsettling copy of a young woman named Elena: same slim build, same shoulder-length chestnut hair parted in the middle, same pale skin and simple outfit — a fitted olive-green jacket, dark jeans, and worn brown leather ankle boots caked with mud. But the face is wrong: enormous round glossy eyes far too large for the head, glassy and staring, with tiny pinprick pupils, and an impossibly wide grin stretching ear to ear, teeth bared in a fixed sinister smile. The head tilts slightly, arms hanging stiffly with fingers a touch too long. She stands among dark twisted trees, thin mist curling low around her muddy boots, faint moonlight catching her huge unblinking eyes.
