Sample Prompts for Testing

Here are some curated prompts designed to showcase the portrait capabilities of the model:

A young boy with curly brown hair and large, curious green eyes stands at the edge of a meadow at dusk. His round face is illuminated by the soft glow of fireflies dancing around him, and his cheeks are flushed from running. He wears a simple white t-shirt with grass stains on the collar and a pair of denim overalls.

The camera captures a close-up of his face as he reaches out to cup a firefly in his small hands, his expression a mix of wonder and excitement. A faint smudge of dirt is visible on his right cheek, and his slightly chapped lips part as he lets out a quiet gasp.

In the background, blurred but softly lit, are tall wildflowers swaying in the breeze and the faint outline of a distant farmhouse. The audio features the gentle chirping of crickets and the soft rustle of leaves, enhancing the scene's magical, nostalgic quality
