Classic Blue Backdrop with Bal Krishna with girl

Use the exact face, hairstyle, and body from the uploaded reference photo of the girl — do not change facial features, skin tone, or expression. Keep the same sitting cross-legged (or as per photo) pose, same outfit and posture as in the reference photo. Add a cute 3D cartoon baby Krishna character (blue skin, curly hair, peacock feather, gold jewelry, yellow dhoti) sitting behind on the shoulder with one arm resting on the shoulder, big expressive eyes, Pixar-style glossy 3D render. Background: soft light blue solid color studio backdrop. At the top, add decorative text 'Happy Janmashtami' in elegant navy-blue and gold vintage calligraphy font with peacock feather illustrations on both sides, and a golden flute illustration below the text. Add '[Girl's Name]' in matching elegant font near the bottom. Format: portrait Instagram post size, 1080x1350 pixels, professional studio photography look. @Create image
