A smiling Brazilian woman with medium-length dark hair, slightly wavy, wearing a casual outfit in warm, neutral tones. She should be posed in three different joyful expressions: one with her hands on her hips and a wide smile, another with her arms raised in excitement and laughing, and a third with her head slightly tilted, giving a warm and friendly smile. The background should be clean and neutral, focusing on her facial expressions and poses. The lighting should be bright and natural, highlighting her happiness and making her appear approachable and friendly.
