Step two, draw the eyes and eyebrows of the swallow. The eyes can be drawn as a small point, and the eyebrows can be drawn as two small meniscus shapes. Swallows' eyes and eyebrows can have some vivid expressions, such as anger and happiness.
Step three, draw the beak and mouth of the swallow. Swallows' beaks are slender and need to draw some radians. The mouth can be drawn as a small arc or triangle, and you can play freely according to your own ideas.
The fourth step is to draw the wings and tails of swallows. Swallows have long wings and tails, so they need to draw some bends to make them look more flexible. If you want to draw some feathers, you can draw more details on the wings and tail.
Step five, draw the body of the swallow. Swallow's body is small and exquisite, so it needs to draw some arcs to make it look more lovely. If you want to draw something with wool texture, you can draw more details on your body.
Step six, draw the outline and details of the swallow with a black watercolor pen or colored pen, and string the pictures together. At this time, we should pay special attention to the lines drawn, especially the wings and tails, and draw the feeling of swallows flying.
Step seven, color. Swallows' bodies are mostly blue and gray. You can add some other colors according to your own ideas, such as yellow, orange and so on, to make the swallows more colorful.
Finally, touch up the decoration. You can add some natural elements such as trees and flowers to the picture, so that the swallows can present a vivid and lovely scene. You can also add some light and shadow to the swallows to make the picture more stereoscopic and realistic.
