Overall:
First, the sketch doesn't grasp the essentials, such as the prefix [Su] and the prefix [Su]. Instead of bending outward, the pen tip is lifted lightly, so there is not such a big bend back.
Second, the structure should be accurate. For example, the characters Gao, Hugh and Le are inclined in the frame structure of the characters, and the strokes are separated, which affects the momentum of the whole character. Although you mentioned that strokes are not connected, you practice brushwork, but brushwork is not practiced like this. Relatively speaking, the strokes of each word must be practiced on the whole of a word, just like writing the word [I], so that each word can be written accurately and for a long time.
In short, your understanding of stippling is basically ok, and every stroke is written in a solid way. This attitude and spirit of learning books is very good.
The next step: we need to pay attention to it in practice: we should write freely. In general, every word should be written with strokes as the main strokes. For example, the word [Gao] should highlight the long horizontal line above the mouth so that the word will be stable. Like the word [I], you highlight the oblique hook, not only to write the oblique hook, but also to stabilize the center of gravity of the word and make the word more powerful, generous and beautiful in the overall composition.
Let's just say. I hope to continue to work hard.
