To learn good sketching skills from scratch, start by mastering basic drawing fundamentals like lines, shapes, and proportions, then gradually progress to more complex techniques like perspective, shading, and anatomy, all while practicing consistently, observing the world around you, and seeking feedback when possible

To improve your sketching, you can practice exercises like: blind contour drawing, gesture drawing, drawing with your non-dominant hand, drawing upside down, focusing on negative space, timed sketches, contour line drawing, practicing basic shapes, and observing and drawing objects from life, including focusing on their proportions and values

The basics of sketching include: understanding basic shapes like circles, squares, and triangles, using light pencil lines to establish outlines, focusing on proportion and perspective, employing shading techniques to create depth, and practicing observation skills to accurately capture what you see; all while using a loose grip on your pencil and making light, fluid strokes to start, refining details later.
