Armored Knight Charging on Black Warhorse

the prompt

A dramatic low-angle cinematic view of a menacing knight in intricate ornate black plate armor and helmet with flowing dark cape, riding a powerful muscular black warhorse in full gallop charging directly toward the viewer across a vast field of tall green grass. The knight raises a long straight sword triumphantly high in his right hand. The horse has a wildly flowing mane and tail whipped by motion, ornate leather-and-metal barding, and tack. Foreground shows extreme radial motion blur streaks in the grass conveying tremendous speed and velocity. Background features towering jagged snow-capped rocky mountain peaks under a vibrant deep blue sky with voluminous dramatic white clouds. Epic dark fantasy atmosphere, highly detailed textures on armor and horse, cinematic high-contrast lighting, dynamic heroic composition.
