Painting step

Scientific and rigorous methods and steps can not only ensure the smooth progress of sketch work, but also cultivate our overall observation and description ability.

1, create a composition

Deliberately arrange the composition, so that the objects on the screen are given appropriate priority, and the composition is balanced and diverse, avoiding the disadvantages of scattering, chaos, emptiness and congestion.

2. Physical structure

Draw the body structure of the object with a long straight line (the invisible part of the object should also be drawn gently), and the shape, proportion and structural relationship of the object should be accurate. Then draw the shape and position of each light and dark level (highlight, bright part, middle color, dark part, projection and intersection of light and dark).

3, gradually in-depth shaping

Through the light and dark description of the body (from the whole to the part, from the big to the small), the sense of volume of the object is gradually shaped. The main and key details should be carefully described.

4. Adjustment completed

In-depth characterization inevitably ignores the relationship between the whole and the parts. At this time, it is necessary to comprehensively adjust (mainly referring to the physical structure including color, texture, space, primary and secondary, etc. ), so as to make a choice and highlight the main body.
