[No BGM] A cinematic transformation sequence that begins as a hand-drawn pencil sketch on white paper. A person is being drawn in rough pencil lines, then the finished sketch comes to life and starts walking naturally within the sketch world. The sketch person approaches a simple drawn door, opens it, and walks through. As the person comes out from the other side of the door, they are now fully real in a live-action scene. The transition should feel magical and smooth: the pencil sketch world stays monochrome and paper-like, while the real world is fully detailed, photorealistic, and naturally lit. The person keeps the same appearance, pose, and movement as they pass through the door, changing from a pencil drawing into a real human without looking like a robotic morph. Use dynamic but elegant camera movement, following the character as they walk toward the door and then gently revealing the realistic world beyond it. Make the contrast between the 2D sketch world and the live-action reality very clear. No text, no logos, no watermark.
