Precautions for painting:

1, pay attention to the light and angle.

Pay attention to the light and angle when drawing, because they will affect the overall effect of the picture. When painting indoors, you should make the best use of light and choose a place with sufficient light. At the same time, we should pay attention to the drawing angle, especially some three-dimensional objects, which need to be observed and described from different angles in order to reflect the shape and characteristics of the objects more accurately.

Step 2 pay attention to lines and shapes

Pay attention to lines and shapes when drawing, because they are the basis of the picture and directly affect the effect of the whole picture. To draw a more realistic and vivid picture, we should be as close to the real shape of things as possible, and pay attention to the thickness of lines and the accuracy of shapes. At the same time, when drawing people or animals, we need to pay attention to the proportional relationship between them and the coordination between different parts.

Step 3 pay attention to colors and materials

You need to pay attention to the choice of color and material when painting, because they will directly affect the color and texture of the picture. To draw more beautiful and delicate pictures, we must choose good quality pigments and brushes and use different colors and textures reasonably. At the same time, we need to pay attention to the collocation and transition of colors to avoid the picture being too messy or monotonous.

4. Pay attention to mentality and temperament

Drawing requires not only skill, but also adjustment of mentality and temperament. Keep a positive attitude and concentration when painting, and don't be disturbed by the outside world. At the same time, we should know how to appreciate works of art, respect the works of ourselves and others, and maintain our love and pursuit of art.
