I did learn descriptive geometry, perspective, technical, mechanical, and architectural drawing in school and I learned to draw and paint autonomously seeing and doing. That being said, I’ve been drawing for over 40 years. (Fine Art, Sketching). Contemporary illustration uses a wide range of styles and techniques, including drawing, painting, printmaking, collage, montage, digital design, multimedia, 3D modelling. Depending on the purpose, illustration may be expressive, stylised, realistic or highly technical.
