I hope people who know calligraphy can give me some advice!

In your strokes, you didn't write the horizontal lines well. Write it one stroke at a time, and don't shake your hands. Also, pay attention to the thickness of the strokes. On the right side of the word "de", the sky is three horizontal, and the bottom is three horizontal, which is too different and uncoordinated. "Heaven", "water" and "coming" are out of proportion. Everything else is well written. I guess your hands shake when you write. I don't know if I'm right. If this is the problem, it's because you haven't practiced enough. I used to have this problem, but I practiced writing 1000 one day without feeling sour or shaking.
