Art winter vacation homework Harvest Write:

This holiday is dominated by oil pastels, line drawing and scraping, supplemented by stickers. The colors of oil pastels are rich and colorful, which can be used in single color, double color and multi-color, and it is easy to show the color change and transition of things. There are no restrictions on composition and layout, and the relationship between front and back positions and the occlusion of things are easy to master. However, the overlapping application of color strokes and colors is not effective, and it will also cause damage to the picture and affect the picture effect. Another advantage of the oil pastel is that it can be used regardless of its size or broken line.
