Focus: Make sure the camera is focused on your face before taking the photo. Otherwise, the result may be a clear shot of the top half of your body and a blurred face.
Stable camera or motion: Try to keep the camera steady for at least the duration of the exposure to avoid blurry or distorted photos.
Edit with care: If you want to edit the photo, do so moderately to preserve its natural beauty. Avoid excessive photo retouching or manipulation that could make the image look artificial.
