From what aspects to evaluate a calligraphy work?

Have an intuitive feeling about the quality of calligraphy works. Most people have this feeling, and even people who don't understand at all can tell a thing or two. Of course, this feeling is not enough for a work of art. I have summarized several points here for reference only. 1. The source can be traced; We can see what kind of teacher is from his works. Second, he is very bookish. What is the author's cultural background? 3. Brush strokes. Whether it is a collection of achievements. 4. Ink method; Whether coarse, fine, coarse and withered are appropriate. 5. structure; Whether the pitch is appropriate, whether the inclination angle is appropriate, 6. Composition, the size of words, the spacing between lines, whether the responses before and after are mixed, 7. Whether the position and momentum of seals, collars and leisure seals are appropriate; Is it contagious to stand in front of the work?
