Chibi Fighter Sprite Sheet

Goal: Create a 2D pixel-art combat motion sprite sheet for a cute chibi anime schoolgirl fighter, designed for animation use. Canvas: Square 1:1 sprite-sheet canvas with a transparent-background checkerboard preview. Arrange exactly 16 separate sprites in a clean 4 x 4 grid, evenly spaced, all facing mostly to the right. No labels, numbers, UI, borders, shadows, or extra effects. Character details: A small chibi girl with {argument name="hair color" default="blue"} messy medium hair, side ponytail, and one curled ahoge strand on top. She has a simple cute anime face with dark blue eyes and a determined but cheerful expression. Outfit: bright {argument name="jacket color" default="yellow"} open jacket with oversized sleeves, lavender shirt, dark navy pleated skirt, white legs, and chunky {argument name="boot color" default="red"} ankle boots. Use thick dark navy pixel outlines, crisp 16-bit/32-bit game sprite style, limited palette, clean cel shading, and consistent character proportions across all frames. Sprite count and poses: Include exactly 16 discrete frames in this order, left to right and top to bottom: 1 standing guard stance with both fists raised, 2 low ready crouched guard, 3 wind-up punch with rear arm pulled back, 4 forward lunge preparation with jacket sweeping back, 5 straight punch extended, 6 deeper straight punch with body leaning forward, 7 returning to guard, 8 balanced guard stance, 9 knee raise preparation, 10 higher knee lift, 11 side kick starting with leg extended horizontally, 12 full high side kick with leg raised near head height, 13 compact knee-up guard, 14 low crouch recovery with one hand near the ground, 15 neutral guard stance, 16 final relaxed guard stance. Composition constraints: Each frame should show the full body, preserve consistent scale and baseline alignment, keep large empty gaps between sprites so they can be sliced cleanly, and make the character readable at small size. The sprite sheet should look like a fighting-game animation cycle for {argument name="character archetype" default="a cheerful chibi schoolgirl martial artist"}.
