1, draw the outline of the fish with lines.

2. Draw a fish's mouth, blacken your eyes and draw fins on your body.

Step 3 draw a fish's tail

4, finally painted with color, simple and beautiful fish is completed.

Fish (scientific name: Piscium) is a general term for aquatic vertebrates with variable temperature. It is covered with bone scales, breathes through gills, swims through the swinging of tail and trunk and the coordinated movements of fins, and feeds on the upper and lower jaws. It belongs to the vertebrate subfamily of Chordata and is the oldest vertebrate. Fish is rich in animal protein and phosphorus, which plays an important role in the development of human physical strength and intelligence.

Spindle-shaped, also known as basic type, is the body shape of general fish, suitable for swimming in water, and the whole body is spindle-shaped and slightly flat. Among the three body axes, the head and tail axis is the longest, the dorsal and abdominal axis is the second, and the left and right axis is the shortest, which makes the whole body streamlined or slightly flat to reduce the resistance when moving in the water, so this fish is good at swimming. Often inhabit the middle and upper water. Examples that can be used for long-distance migration: carp, crucian carp and shark.

The main points of painting:

1, learn from decorative painting. Picture segmentation, point, line and plane composition, visual balance, rhythm of picture element arrangement. Color collocation, color distribution and so on, color psychology. Starting from learning the most basic laws of visual aesthetics, it will be of great help to art study at any stage in the future.

2. Then sketch painting began to learn. Learn from structure sketch, and express the structural relationship and spatial perspective relationship with lines. From simple geometry to complex geometry, to plaster head and still life sketch. Learn how to brush and draw smooth lines. The purpose is to learn to express the spatial structure of objects.
