For Image Generation:

PROMPT:
First of all generate a picture with your image in Nano Banana or Gemini.

Upload your picture select Aspect Ratio 9:16 and use this Prompt:
A hyper-realistic cinematic scene in a snowy Himalayan mountain environment. The main character is sitting confidently on the back of a powerful, dangerous Tasmanian snow tiger. Use the exact face from the reference image without changing any facial features or proportions. Keep the hairstyle and skin details identical to the reference. The character is wearing adventurous winter clothing suitable for extreme cold conditions. The snow tiger looks fierce, muscular, and majestic with sharp eyes and thick white-striped fur. Snow is falling lightly and strong wind blows through the mountains. Dramatic sunlight breaks through clouds from behind, creating epic atmosphere and depth. The camera is in front-angle medium-shot, capturing the character, tiger, and mountains behind them clearly. Ultra realistic lighting, detailed textures, crisp shadows, 8K photographic quality.

For Video Generation:

PROMPT:
Use that generated Picture in VEO3 and make a video

Go to Google Flow, select Frames to Video and upload the picture as the starting frame and keep the ending frame empty. And use this Prompt:

Continue the same scene from the still image. The character with the exact same face from the reference remains sitting on the fierce Tasmanian snow tiger. The tiger begins running forward through the snowy mountain terrain, powerful and fast, body moving naturally with realistic muscle motion and breathing. Snow kicks up under its paws as it sprints. The rider holds steady while the movement makes the body react slightly up and down, flowing naturally with the tiger’s motion. The camera tracks smoothly in front of them, maintaining a dramatic cinematic shot. Keep lighting, atmosphere, clothing, facial details, and overall style identical to the reference frame. Ultra-realistic animation, physics-based movement, intense action energy.

Continue directly from the reference frame. The camera remains behind the rider and the running snow tiger. Keep the rider’s clothing, body shape, and all visual details identical to the reference, including the snowy mountain environment, lighting, and atmosphere.

From the front, a massive and fierce Snow Tasmanian Ice Lion charges toward them at high speed. The lion is huge, muscular, with sharp icy fur, glowing cold breath, and frost particles trailing from its paws. As the lion approaches, the tiger roars loudly and leaps into combat. The rider reacts naturally, holding tightly to the tiger while tension rises.

The tiger and lion collide in an intense, realistic animal fight: claws striking, snow blasting into the air, powerful body movements, aggressive growls, cinematic camera shake from the impact. Maintain ultra-realistic animation, physics-accurate motion, and dramatic sound and atmosphere. The camera continues to follow from behind to capture the clash clearly in the center of the frame.

Epic action, 8K cinematic detail, high contrast, snow particles flying, adrenaline-filled fight.
