Sloppy Doodle Cat Portrait

Create an ultra-minimal, charmingly clumsy hand-drawn doodle of a cute {argument name="animal" default="white cat"} on a clean pure white paper background. Show a close-up portrait with the head filling most of the square canvas, slightly cropped at the body, with two tall pointed ears, a rounded face, simple whiskers, and a tiny straight-line smile. Use messy black pen scribble line art with imperfect repeated contour lines and uneven hatching. Add rough crayon coloring: pale cream-white fur, {argument name="patch color" default="black"} scribbled markings across the top of the head and around one side of the face, soft pink inside both ears, a pink nose, and large round glossy eyes with {argument name="eye color" default="golden yellow"} rings and black scribbled pupils with small white highlights. Keep the style deliberately sloppy, childlike, cute, minimal, and airy, with lots of blank white space, no text, no border, no realistic rendering, and no polished vector lines.
