A cheerful baby alligator waves before a giant green letter A

Create a high-quality, adorable 3D cartoon illustration for a children's ABC nursery rhyme. A giant, bold, uppercase letter "A" stands upright in the background, occupying most of the image. The letter A is bright green with a thick, smooth, rounded 3D design. In front of the letter, place a cute baby alligator with big sparkling eyes, a friendly smile, a rounded snout, tiny white teeth, and short little legs. The alligator is waving happily at the viewer. Add a few green leaves and small flowers around its feet. Use vibrant colours, soft studio lighting, gentle shadows, smooth textures, and a cheerful preschool animation aesthetic. Keep the letter A clearly visible behind the animal. Simple, uncluttered background with a light blue sky and soft green ground. Centered composition, eye-level camera angle, professional 3D children's animation quality, extremely cute character design, 16:9 widescreen aspect ratio. No extra letters, no words, no watermark.
