Portrait — Side-by-Side Results
Prompt
"Portrait photo of a 20s woman with shoulder-length wavy dark hair, minimal makeup, wearing an oversized gray hoodie and black leggings, holding her phone slightly above eye level for a casual selfie and glancing near the camera with a relaxed half-smile. She’s standing by a bright kitchen window with a mug and cereal box on the counter behind her, morning natural light on her face, shallow depth of field with soft bokeh and an 85mm portrait feel. Authentic “good morning / busy day” UGC vibe, slightly imperfect framing like an Instagram story."
