Use case: stylized-concept
Asset type: Fighting in the Streets animated storm cloud canopy raster atlas.
Create a genuinely transparent RGBA game animation sheet with EIGHT equal 16:9 panels, strict 4columns x2rows, row-major animation order. Request native3840x1080 detail. Every cell is the SAME continuous broad storm canopy from a fixed camera, hand-painted rich blue-gray and charcoal cumulonimbus. Heavy rolling turbulent undersides cover the upper 65% of each cell, multiple internal depths and illuminated folds; wispy lowered ragged shelf-cloud edge fades to genuine alpha below. Dense full-width turbulent clouds, NOT separate small cloud puffs or little floating clouds. Big dangerous weather front.
Animate coherent roiling motion: frame0 dark towering mass gathering,1 folds billow,2 lower shelf grows,3 dark turbulent curls expand,4 internal rain-lit pale folds brighten slightly,5 rolling front compresses,6 curls reform,7 smoothly approaches frame0. Keep broad silhouette and camera identical, cloud structure evolves subtly and continuously, no sudden scene changes. No cell labels/borders/gutters, each canopy spans cell width without anotherframe bleed; clearalpha in lower third. No background sky color, no ground, no people, no celestial bodies, no rain streaks, no lightning bolts, no flashes, no circles. All sky and precipitation are separately animated game layers. Original painted raster anime arcade background cloud forms, shaded volumetric detail, no vector art. Real transparency, no white/backdrop/checkerboard drawings.
