Crude Geometric Blue-Haired Elf Girl

Create a simple flat 2D digital drawing that looks like it was drawn programmatically with basic polygon and line shapes on a plain light gray background. Center a front-facing anime-style girl bust with a large round peach face, pointed elf ears extending left and right, and a small smiling mouth. She has {argument name="hair color" default="light sky blue"} hair made of angular geometric panels: two long rectangular side locks hanging down on both sides, a central split fringe with sharp triangular bangs, and a dark blue curved back-hair shape behind the head. Her eyes are large but simply drawn, with black outlines, white sclera, red irises, dark pupils, and thin gray eyebrows; add a tiny pale pink dot nose. The character wears a plain oversized white trapezoid shirt with very thin gray outlines, a short peach neck, and two faint diagonal gray collar lines; include two simple circular white shoulder or sleeve shapes partially visible behind the shirt. Use minimal shading, thin black/gray outlines, visible polygon edges, and an intentionally crude handmade/Pillow-like aesthetic. Keep the composition symmetrical, with the head occupying the upper center and the shirt filling the lower half. The character should resemble a cute elf-eared anime girl named {argument name="character name" default="a blue-haired elf girl"}, with no text, no watermark, and no detailed background.
