Sketching is actually the most straightforward. You can use a pencil or anything you can draw to draw a sketch. But the sketch looks simple, but it is not easy to draw well. If you want to learn to sketch, it is best to start from the basics.
The sketching tools are varied and colorful. Just choose the right sketching tool, and then use the random lines to express the outlines and expressions of the characters.
The sketches collected for everyone today are simple and easy to learn, and they are also very nice to draw. As long as you master the specific shape of the item and the point of the transition structure, then the light and dark changes of the color, plus some patience, can basically achieve the desired effect.
