I have taught myself calligraphy for several years and haven't communicated with anyone. I don't know how far I have practiced. Please comment.

Although you have a satisfactory answer, I still can't help but criticize:

Judging from your appearance, you mainly study facial expressions, right? Basically grasped the characteristics of Yan body extension and Si. The last picture can basically be regarded as the vein of the body. However, if you want to learn Yan Ti, you should write more fully. Yandi is characterized by a large lattice. Although you folded the grid, it is still not big enough to show the feeling of atmosphere.

As for your official script, you have mixed it with regular script. In fact, you can't bend the corner horizontally. You should start writing with another pen. Pay attention to the silkworm head and goose tail, which is obvious in Cao Quanbei. Another feature of Cao Quan is that the font is very flat, and the middle palace is tightened and let go. Your writing is too square, even very long, which is wrong. And your points are not vivid, they all point to one point. Dot is the most difficult stippling of a word, and it is not easy to write vividly.

From a professional point of view, you don't have to worry about learning a variety at the same time, because calligraphy majors all take calligraphy at the same time. As long as you work hard, you don't have to worry about learning strings.

Besides, your composition is also very poor. To understand the relationship between opening and closing, your words should be clear and clear, and the words should be to the right, "fighting" with the lang on the right. The center of gravity in the sky is too high and the writing is too peaceful. Better write it clearly. I think this should be because you don't have a good grasp of the font structure. As long as your font structure is accurate, your composition will naturally look better. Moreover, the signature does not belong to the following statement. You should fall to the left of the clear word, and leave a space when folding the grid.

The reason I summed up is that you didn't study hard enough. Just as a hobby, there is no solid basic skills. The key is that your modeling ability is not good enough. I suggest you practice Tian Zige more.
