Image compare: sdxl vs flux2-klein

Animate this exact image without changing its design, composition, colors, architecture, envelope, seal, or any visual details.

The scene begins completely still and elegant.

The luxury blue envelope remains centered in the foreground. After a brief pause, the envelope slowly and naturally opens by itself, as if revealing a magical invitation.

A soft, elegant blue mist gently emerges from inside the envelope and slowly flows upward and outward. Add a few very subtle sparkling particles floating through the air.

The golden seal marked “15” must remain intact and clearly visible until the envelope begins to open.

Use a very slow cinematic camera push-in toward the envelope.

The castle and palace background must remain slightly blurred and atmospheric, with subtle candlelight and soft blue illumination.

Motion must be elegant, realistic, slow and luxurious, like a high-end royal birthday invitation.

Do NOT change the envelope design.
Do NOT change the castle.
Do NOT add people.
Do NOT add text.
Do NOT deform the seal.
Do NOT create extra objects.
Do NOT make the camera shake.
Do NOT use fast movements.
Do NOT make the scene look cartoonish.

The only major movements should be:
1. the envelope opening slowly,
2. soft blue mist emerging,
3. subtle floating particles,
4. an extremely gentle camera push-in.

Cinematic fairytale atmosphere, sophisticated princess aesthetic, premium luxury invitation film.
