Pencil Lines & Textures
If you’re a beginner, focus on learning the drawing process rather than completing the final product for now. Hold your pencil or charcoal with a relaxed grip so your lines flow easily, keeping your approach simple and direct. First make note of the overall shape of the subject, and sketch a few light guidelines from your observations. Once those are correct, make a preliminary drawing, concentrating on basic line angles, shapes, and masses.
Remember that a sure pencil line doesn’t just come from talent; it comes from practice. Study the various types of textures and strokes shown on this page, and do some practice exercises. Give the fish some scales, add bricks to the stone wall, or foliage to the trees.
