界面稿 GPT Image 2 提示词：Storm Wizard Casting Lightning

A dramatic dark-fantasy portrait of an elderly wizard standing in a stormy wasteland under a black, cloud-choked sky. He wears a tall, weathered pointed hat with a brown leather band and a tiny metal clasp, and a heavy dark blue-gray robe with wide sleeves. His face is mostly hidden in shadow beneath the hat brim, with long strands of glowing {argument name="accent hair color" default="electric blue"} hair peeking out at the sides and a very long flowing silver-white beard reaching down his chest. The wizard thrusts his left hand toward the camera in a powerful forced-perspective pose, fingers spread, conjuring a bright orb of blue-white magical energy in his palm with crackling lightning arcs wrapping around the hand and sleeve. In his right arm he clutches a large ancient leather spellbook with worn corners, metal fittings, embossed arcane markings on the cover, and a few pages visible. The background shows a barren dark landscape and exactly 1 prominent lightning bolt striking on the right side of the frame. Cinematic high-contrast lighting, hyper-detailed skin and fabric texture, moody photorealism, sharp focus on the hand and beard, intense fantasy atmosphere, centered composition, square crop.
