To draw Iron Man, start with basic shapes for the body and head. Sketch the outline of his armor, emphasizing sleek lines and detailing the arc reactor on his chest. Add in his iconic mask, with angular eye cutouts and a triangular shape for the face. Use shading and highlights to give the armor a metallic appearance, and don’t forget his repulsor beams on his hands and feet. Finally, add any additional details like his jet boots or weaponry.
