A 3rd birthday milestone photo collage poster for a toddler girl set against a clean off-white studio background. 

The composition features:

1. Left Side: A giant 3D white number "3" shaped frame filled with a photo collage of 8 small pictures showing the same toddler girl in various cute poses and outfits.

2. Right Side: A large, soft-faded black-and-white close-up portrait of the toddler in the background. In front, the same toddler stands in full color making a cute pout face with pigtails.

3. To keep the design completely unique, she wears a soft pastel-pink tulle princess dress with pearl waist flowers and white shoes.

Bottom typography features gold cursive text reading "HAPPY Birthday" above a large pink name title reading "ANANYA" and subtext "Little Princess • Endless Happiness". Clean studio lighting, editorial graphic layout, 8k resolution.
