Use the provided drawing as the absolute reference. Convert this 2D concept into a clean, high-detail 3D sculpt while preserving the exact silhouette, proportions, facial expression, and pose. Do not redesign or reinterpret the character. The character is a tall, extremely thin humanoid demon with a large head and a long neck. One arm is raised, with the hand resting against the side of the head. The body is smooth and slender with subtle anatomical definition. The face is the main focus. Preserve the large sinister smile with individually sculpted long triangular teeth. The mouth must be deeply recessed, with thick lips framing the teeth. The eyes are narrow, relaxed, and slightly smiling, giving the creature a calm but unsettling expression.
