Pixel Art Character Sprite Sheet

Unify the face, hairstyle, outfit, color scheme, and physique of the attached character, and generate {argument name="motion count" default="4 types"} of {argument name="style" default="pixel art"} motions that look great in a game, all on a single sprite sheet image with a maximum of 4 frames each. The size of each frame is {argument name="frame size" default="256x256px"}.
- Run: Lean the body forward, moving limbs in large alternating movements.
- Jump: Crouch → Jump up → Spread limbs in the air → Land.
- Spin Attack: Front → Side → Back → Opposite side, performing one full rotation of the body.
- Fall: Stumble → Tilt sideways → Lie down → Close eyes and stop moving.
Arrange one action per row in a horizontal line, ensuring all cell sizes, feet alignment, center, and scale are uniform. The background must be a completely solid color; do not use shadows, text, frames, numbers, UI, blur, semi-transparency, gradients, or anti-aliasing. Ensure looping actions connect naturally between the start and end.
