The Basic Principles of Lines Lines are one of the most fundamental and essential elements in drawing. Using a pen, we can create various shapes, thicknesses, and textures of lines. Basic line exercises include straight lines, curved lines, and wavy lines, which can help improve hand stability and control of the pen. 2. Thickness and Shading of Lines Mastering the thickness and shading of lines is key to drawing. Thick lines can create a strong sense of power, while thin lines are more delicate and exquisite. By changing the depth of the lines, different light and shadow effects and the three-dimensional sense of objects can be expressed. 3. Combination and Application of Lines In drawing, a single line often cannot express a rich picture effect. Therefore, we need to combine and match different lines through crossing, overlapping, and spacing techniques to make the picture more vivid and interesting. **Part Two: Advanced Skills** 1. Creativity and Imagination After mastering the basic skills, we can start to add our own creativity and imagination. Using the line art of a pen, we can create various unique patterns and designs such as anime, illustrations, sketches, etc. 2. Perspective and Composition Perspective and composition are very important skills in drawing. Mastering the principles of perspective can show the distance relationship and sense of space of objects; while composition determines the layout and visual effect of the picture. The line art of a pen can be used to better practice perspective and composition.
