Clear front-facing photos provide a stronger reference for preserving the person's hairstyle, facial structure, skin texture, lighting, and overall appearance while the expression is adjusted.
Flexible Smile Mood
Explore different emotional styles, from a subtle closed-mouth smile and friendly expression to a brighter cheerful look, then generate and compare multiple variations to find the best fit for your portrait.
