Nine-Angle Stylized Male Avatar Grid

Create a 3x3 grid of nine stylized digital portrait avatars on a clean white background, all depicting the same young man with curly dark brown hair, a trimmed beard and mustache, and a soul patch under his lower lip. He wears a charcoal gray suit jacket over a crisp white collared shirt. The art style is smooth, semi-realistic 3D rendering reminiscent of modern app profile pictures, with soft studio lighting and gentle skin shading. Arrange the nine heads in three rows to show different gaze directions: top row looking upward (left, center, right), middle row looking straight ahead or slightly sideways at eye level, bottom row looking downward. Keep facial features consistent across all nine panels while varying only head angle and eye direction.
