"Create a highly detailed, realistic image of Itachi Uchiha from the Naruto series. He should be shown in a serene environment, with a gentle smile on his face. His eyes should be calm and peaceful, with a hint of sadness. He should be placing his finger on Sasuke's forehead, as if imparting a final lesson or blessing. Itachi's face should be pale and gaunt, with a subtle hint of exhaustion and weariness. The image should be rendered in a muted color palette, with soft lighting and subtle shadows. Focus on capturing the emotional depth and complexity of Itachi's character in this poignant moment."
