Use case: identity-preserve. Asset type: exact production top-down JRPG sprite animation sheet, transparent. Edit target: supplied Bridgeburner commander sheet. Preserve SAME young adult character, brown hair, grey cloak, dark steel armour, bridge-and-red-flames brooch, sword scabbard on his anatomical LEFT hip. No design change. Replace the animation with a real expressive but grounded brisk WALK CYCLE. Six columns by four rows, exactly 24 isolated figures. ROW1 faces SOUTH, ROW2 WEST, ROW3 EAST, ROW4 NORTH. Every row keeps that exact direction in all six frames. Same orthographic slightly overhead camera, scale, head shape, hairstyle, face, eye positions, torso widths and equipment placement throughout each row. All heads in a row must be pixel-identical except a tiny one-pixel vertical body bob. No eye blinking. Columns are six successive walk phases: 1 left-foot forward contact/right arm forward, 2 weight down/support knee flexed, 3 passing pose with right knee clearly lifted and left arm moving forward, 4 right-foot forward contact/left arm forward, 5 weight down on right foot, 6 opposite passing pose with left knee lifted. Arms counter-swing visibly from the shoulders, elbows relaxed, hands away from belt; boots and knees visibly articulate. Legs alternate, never repeated same-leg strides. Natural confident walking, not running, marching, shuffling or standing rigidly. Use large SIMPLE readable pixel clusters and simplify tiny armour textures that shimmer. Keep hair, eyes, facial marks, brooch, chest plate, belt and scabbard invariant. The commander burn belongs only on anatomical LEFT cheek; do not mirror equipment between adjacent columns. Hair must not deform from frame to frame. No smear frames, ghost silhouettes, translucency, blur, antialiasing, shadows, particles or motion lines. Each figure fits a 48x64 LOGICAL cell, adult standing height about56 pixels. Draw this sheet as a magnified pixel sprite atlas, with generous fully transparent gutters between all figures for slicing, equal spacing. Landscape six columns/four rows, NOT three columns. No labels, text, grid, border or scenery. Real alpha transparency.
