How can I write beautiful English calligraphy? Why can't you keep practicing?

I bought the junior high school student who specializes in calligraphy. I bought a book with 26 letters. I practiced for two months in senior three, and the teacher said that my writing was beautiful. Then she attached great importance to it and asked the whole class to buy calligraphy practitioners to practice together. As a result, our classmates' handwriting is beautiful. In fact, as long as we try to write bigger, rounder and fuller like Yang Guifei, it will look good. It's best not to be handsome and write conjoined characters, just write and write at ordinary times. Teachers like to print at a 75-degree tilt, taking clean wings as the standard. It doesn't matter what copybook you choose, but you should be single-minded
