Design a pixel art anime avatar, showcasing the iconic anime style with large expressive eyes, elaborately styled hair, and vibrant colors. The character should be in a classic anime pose, exuding personality and emotion typical of anime characters, like excitement, determination, or serenity. Focus on creating a highly pixelated aesthetic, reminiscent of 16-bit video game graphics, where each pixel is clearly visible and contributes to the overall form and expression of the avatar.
