This is a sketch that I just learned. Let's talk about the problem.

I'm sure you have too many questions. The people upstairs have a point. I don't think you can understand much after reading it. I just want to say that everything you have is wrong.

1 everyone upstairs says this is easy to solve. Just read more books in Central America and America. Every book analyzes its composition. If you don't know what this is, just ask. This can't be said that remembering a principle is broad, but you can't take care of it.

Your main goal is black cans. You need to know the boundary between light and shade. Look at the others. You know it's too stuck. What about the curved jar above? Don't you think it's too fake? There must be more light on the front than on the side, so the side must be dark. Touch the jar with your hand and see where it is. Your teacher must have said that you needed a single light source. Guess what you did should be a little backlit. Pick a good place. It's not easy to observe Besides, your studio is so open. The electric rod must be so bright, and the glaze of the jar should be so bright. How can I draw well? What about the reflection of the jar? You didn't leave the edge line. It's not true that the apple's projection on the jar is not so bright. Let's ash it.

Do you think an apple is like a knife?

The boundary between light and shade should be pasted, but not so heavy. It is correct to weaken the apple's projection, but the projection also has a shape. Find the shape of the projection. Does the projection of the jar also have a shape? The projection of the apple in the back is lighter, but it can be seen that the projection of your jar is light and shapeless.

4 plates Dear students, why do other things have projections and plates don't? You look down on him, such a plate is like an empty plate floating on a cloth.

5 interlining interlining is to set off other objects, and it is not necessary to draw a trace of softness. People are how soft the cloth is. Draw a texture, rub a little more, wipe the lines with paper, and draw more strokes, but lighter. The lighter part is not a line, but a lighter stroke, so it looks like an unfinished painting. Nothing else.

In short, I don't think you understand what your teacher said. Your teacher must ask you to find the shape of the apple on the bottle. As a result, your painting is too light, which makes you draw the dividing line between light and dark. The results also let you find the changes of light and shade before and after the left and right. As a result, you didn't draw too much, so I asked you to find the projection results. You forgot the plate. Anyway, all kinds of problems are common mistakes made by novices. Painting is no problem. Do you think what you see now is so rare that others can't see what they can draw and they can't draw it themselves? This is normal. Slowly, you will draw better and better. When you see this picture yourself, you will laugh. Nothing else. But your black, white and gray are well handled, at least the picture is not very gray, and it seems that the jar can still hold paper, which is very good! ! !
