Pixel Art Sprite Sheet Creator

Before translationTransform the character in Image 1 into a high-quality 2D pixel art game character, generating a square 4x4 grid sprite sheet with 16 continuous action frames. Each grid cell must be the exact same size, playing in order from left to right and top to bottom. Strictly preserve the character's face, hairstyle, body type, clothing colors, signature accessories, and weapon structure. Use consistent pixel scaling, character size, orientation, and color palette across all 16 frames. The character performs one sword attack / jump / roll / spellcast / pounce sequence. Frames 1-3 are idle and charging; 4-7 are weight shifting and movement initiation; 8-10 are the main attack and power release; 11-13 are inertia and recovery; 14-16 return to idle, with frame 16 looping naturally back to frame 1. Adjacent frames should only change the joints, outlines, clothing, hair, and weapon positions needed for the action, maintaining consistent motion trajectories. All cells must maintain the same camera angle, character scale, baseline, and center. Display the character in full without cropping. The background should prioritize transparent channel; if unstable, use a solid color background. Do not generate scenes, floor textures, grid lines, numbers, or text. Use clean hard-edge pixels with a limited palette and uniform density. No blurring, anti-aliasing, semi-realistic rendering, repeated frames, or character distortion.
