Pay attention to the structure of words. Compare your handwriting with that of famous writers.
If the basics are not good, you should write more posts. Needless to say.
If you think your handwriting is really ugly, you can observe the posture of running script. This is a very high level. (If you don’t have a solid foundation in regular script, it’s best not to start practicing running script too early)
It’s very difficult for beginners to write as spiritually as a calligrapher.
You should first practice the basics well, and you must be familiar with the operation of individual strokes.
I don’t know your specific situation. I hope this will be helpful to you.
