Portrait2:3 majestic photoreal white horse rearing upward out of dense clouds, viewed from directly below with strong foreshortening. Muzzle points upward-left at x34%,y18%; neck rises through center, mane streaming in delicate white strands toward right x76%,y48%; ears around x61%,y26%. Muscular chest occupies x25–73%,y47–78%, one bent foreleg projects toward viewer with knee near x45%,y71%, lower body dissolves behind clouds at bottom fifth. Deep desaturated blue sky remains visible across top-left and around head. Thick cumulus clouds frame bottom and sides, with brilliant silver edges at upper-right, lower-right and lower-left. Strong sun from upper-right/back makes mane rim and right chest luminous ivory; left face and neck are cool blue-gray shadows with detailed short fur. Atmospheric light shafts and fine translucent flyaway hairs, massive but anatomically plausible horse. No rider or wings, no ground, no text.
