Create a PNGTuber character portrait of a cute yet stern-looking girl with long, straight black hair and pointed elf ears. She is not wearing a hoodie, and her eyes are bright orange with a beautiful star-shaped, five-pointed pattern in the pupils, giving her an intense and sharp gaze. In the image, show her in two separate poses: on the left side, she has a calm, silent, and serious look, exuding coolness and aloofness, while on the right side, she is speaking, with her lips slightly parted but still appearing distant and reserved. The expressions should be nearly identical in appearance but with slight differences to show the shift from silence to speech. Use soft lighting to enhance her cool, reserved aura, while still keeping her cute features
