How to make a faces 3D model look correct?

To make a face 3D model look correct, prioritize accurate facial proportions, clean topology for natural deformation, and realistic texture/lighting that mimics real skin. Accurate proportions align features to standard landmarks—like eyes at mid-head height or nose width matching inner eye distance. Clean topology uses edge loops around eyes and mouth to ensure smooth movement when animating. Realistic textures add subtle details (pores, fine wrinkles), while soft directional lighting highlights contours without harsh shadows. Start with a 2D reference photo to guide shaping, use sculpting tools (Blender, ZBrush) to refine details, and test under different lighting to tweak for realism.
