Pixel Art Character Animation Sprite Sheet

Keeping the face, hairstyle, outfit, color scheme, and physique of the reference [character] strictly consistent, generate four pixel art animation cycles for a 2D game on a single sprite sheet. Each motion is arranged in its own horizontal row with exactly 4 frames per row (each frame 256x256 px): - Row 1 ([Running]): Leaning forward with limbs swinging in a wide running cycle. - Row 2 ([Jumping]): Squat preparation → upward leap → spreading limbs in mid-air → landing. - Row 3 (Whirlwind Attack): Front view → side view → back view → opposite side view, completing a full 360-degree body rotation. - Row 4 (Falling): Staggering backward → tilting sideways → collapsing to the ground → lying motionless with eyes closed. Composition and style: Pixel art sprite sheet on a solid single-color background. Align character height, ground baseline, center axis, and scale across all cells. Looping actions must connect seamlessly between start and end. Pure crisp pixel clusters; no anti-aliasing, no drop shadows, no gradients, no semi-transparency, no grid borders, no text, no UI.
