Anima un avatar 3D con Veo3

animate this head and let him say: [Hey, I'm the Amir's clone - and today I'm gonna speak to you for him, because he's sleeping again. What's your question?] The head should be floating precisely in the center of a [dark grainy] background. The head has [short, dark, slightly messy] hair and reflective, symmetrical eyes. Start with a [calm] expression, lips closed, with occasional gentle blinks. The head remains floating, slowly and smoothly turning side to side to create a natural motion throughout the sequence. Emphasize realism, smooth transitions, and high detail in the textures and movements.
