AI Video Prompt: Magical Rainbow Cloud Waterfall Over a Forest Lake…

A single continuous cinematic vertical 9:16 fantasy nature shot showing a giant fluffy glowing cloud floating above a peaceful forest lake. The cloud remains positioned in the upper center of the frame and releases multiple vertical streams of rainbow-colored luminous water-like light falling downward like a magical waterfall. The streams contain blue, green, yellow, orange, pink and purple glowing tones and softly illuminate the lake surface below with realistic reflections. Surrounding the scene is a dense evergreen forest with natural rocks around the water edge. The atmosphere is calm, mystical and dreamlike with realistic cloud textures, cinematic lighting, soft atmospheric glow and detailed environmental depth. Keep the camera completely locked in a wide cinematic shot with no cuts, no zoom, no camera movement. Maintain the exact cloud shape, forest layout, lake position and magical waterfall effect throughout the entire video. No characters, no extra objects, no scene changes, realistic physics and natural gravity.
