Why do you always draw different pictures?

What they say is nonsense. If there is anything wrong, just point it out and chirp silently. Just look at the photos and paintings you gave me. Your foundation is rather weak and your observation is average. Now I point out your problem. Your painting is basically fat, with a fat chin, a long mouth and big eyes. There is no obvious boundary between light and shade, no obvious light and shade, loose structure, loose brushwork and no definite lines. You deliberately chose a colorful sketch paper, which can't express yourself at all, but makes the picture more difficult to distinguish. I believe you should know how to deal with so many problems. Diligence is one thing, and then laying a solid foundation is another. You can't let others find fault with your modeling ability, or you might as well paint Chinese paintings. Sketch is purely rational and must be taken seriously objectively. Besides, you said you taught yourself. I can understand that self-study can paint like this, which also shows that you are very diligent, but I still give you a suggestion. You can sign up for a painting class to learn, so that you can lay a solid foundation. All right, that's all for now. You can add my friends to discuss and study together. Maybe what I said earlier was a little harsh. I don't like beating around the bush. Please forgive me.
