To create a realistic texture on the avocado skin, you can use different shading techniques such as crosshatching, stippling, or blending. Start by shading the avocado skin with a light layer of color, and then gradually build up darker shades to create depth and texture. You can also use a reference image to guide your shading and observe the natural patterns and shadows on the avocado skin. By following our drawing tutorial, we will take you step-by-step through the texturing process!
