Avoid showing multiple limbs or faces, disfigurement, blurry features, poor anatomy, or any elements that would distort her ethereal, serene demeanor. No mutated features, additional heads, or extra appendages. Keep the focus on a single, harmonious portrait without any distracting elements such as text, logos, or watermarks. The composition should be free from grainy textures, oversaturation, and unwanted noise, ensuring a clear and focused depiction of the alien girl.
