Command: Using the nano-banana model, create a realistic, promotional-style image of a 1/7 scale commercialized figure based on the character in the illustration. The scene is set during the golden hour, casting a warm, celebratory glow. The character stands in a dynamic pose on a circular, transparent acrylic base, placed on a wooden desk. Next to the figure, displays a collector's edition packaging box featuring the original artwork and a clear Google Gemini logo on the front. Place some Vietnamese chess upright on the desk. The desk is positioned as if on a balcony, overlooking a city street alive with an Independence Day celebration. The background should be a slightly blurred, festive parade with Vietnamese red flags and confetti in the air. The final mood should be chic, proud, and vibrant—a contemporary tribute to national heritage, with the figure as the distinct centerpiece.
