First, judging from the single word, there is still a gap with the original post. For example, the first word "Ding", the original post is straight and neat, and if it is bent, its strength will be weak; The length and width are inclined, and the left side is long and the right side is short. I suggest you carefully observe the structure of each word, practice word by word, wait until the structural brushwork looks like the original post, and then come line by line, and finally the whole article will come in.
Second, from the overall composition, it is slightly crowded, and the row spacing can be slightly looser.
It is urgent to practice calligraphy. I wish you progress every day.
