Minimalist Single Line Social Media Avatar

Please convert the input image into a minimalist line drawing suitable for social media profile pictures, with a default aspect ratio of 1:1. The subject can be a person, cat, dog, other animal, or plant. Based on the type of input subject, automatically extract the most recognizable outline and key features, summarizing them into an artistic, minimalist line drawing profile picture/illustration. The overall goal is not mechanical outlining, but preserving the subject's spirit and recognizability, reconstructing it in a more elegant and spirited way using single lines. [Subject Processing Logic] If the subject is a person: retain key outlines such as face shape, forehead, nose bridge transition, mouth transition, chin, ears, and hairstyle, retaining only necessary facial features and avoiding cluttered details. If the subject is an animal: retain the head shape, ears, nose and mouth outline, eyes, and the main direction of fur, avoiding complex details. If the subject is a plant: retain the most recognizable morphological features of flowers, leaves, branches, or fruits, summarizing their posture and rhythm with simple lines. [Line Style Requirements] Lines must be rounded, flowing, bold, and natural, as continuous as possible, with a sense of breath and improvisation. Use soft curves, avoiding sharp, harsh, or rigid lines. Avoid stiff, logo-like outlines. Lines should be simple yet vibrant, with a touch of casual artistry, appearing relaxed and collectible. [Composition and Portrait Fit] 1:1 square design. The subject should be clear, focused, and prominent. Use a centered or slightly off-center composition with a clear visual focus and ample white space. [Background Logic] Don't fixate on one color (not always blue). Choose a dark background logic based on the image's tone. Avoid neon colors or cheap bright colors. [Line Color Logic] Use thin white or light-colored lines that contrast with the background. [Embellishing Logic] Add a few random colored dots, curves, stars, or geometric symbols to enhance vibrancy and fun. Keep it sparse and natural. [Overall Goal] Minimalist, light, modern, and artistic. Suitable for social media: eye-catching, easily recognizable, and fun. [Avoid] Realism, shadows, textures, complex scenes, mechanical outlines. 16:9 aspect ratio.
