Who he is

Cosmo is an original character - a 19-year-old man with a lean, athletic build, fair skin, short wavy dirty-blond hair, and an easy boy-next-door look. Modern and casual: streetwear and denim on the street, flannel indoors, poolside in summer. Not based on any real person.

How to use

What it does well

Holds a consistent face and build across full-body, three-quarter, and seated compositions, in both daylight and warm interior light. Strongest in casual and streetwear looks.

Notes

Cosmo is an adult character, 19 years old.

Sample coverage so far is full-body and mid-shot, so tight close-up portraits are less proven. Expect to tune weight around 0.7 for face-only crops.
