First, the overall composition and layout, sometimes each word doesn't look particularly beautiful, but it is more beautiful when put together. The main concern is uniformity, the shade of ink, the matching of size and thickness, etc. There are too many things to generalize, but often good works will give people a strong visual impact. If you want to improve your appreciation ability in this respect, you need to read more posts and pay attention to celebrities' evaluation of copybooks. After repeated thinking, you will gradually improve them.
Second, every word is beautiful and generous. Just like the example in the above picture, the first word is balanced and looks stable, and it really feels better than the last two words. However, the last two words cannot simply say that he is not good-looking. The first thing to consider is the font and brushwork. All three characters are official scripts, which are in place in brushwork. They are all official scripts, like whole words, with fewer strokes. Look at that. Secondly, we should know that the above picture is an inscription, and some natural flaws are also a kind of taste, but the first word is particularly beautiful and has a golden stone flavor, which is due to luck and has nothing to do with the writer's calligraphy level; Finally, it depends on the pen and ink. Is it a winger or a center? Is the three-dimensional sense of strokes strong? The strength and humidity of ink will affect the beauty of words, but because the picture is an inscription, the situation of using ink with a pen is unknown.
The above is my humble opinion for your reference.
