I want to ask a master calligrapher to give me some advice. I really appreciate your help.

I'm no expert. After reading your handwriting, I have the following feelings: temporary strokes are actually clearly explained, and monosyllables are basically inseparable. The key is that there are many mistakes in your brushwork, which reflects your misunderstanding of brushwork (explain clearly, but don't be casual, otherwise the discerning person will see your impetuousness at a glance). After several months of practice, it shows that you are very talented. I suggest you pay attention to the thickness of strokes, which will make your calligraphy by going up one flight of stairs.

If you want to improve, I suggest practicing with a brush copybook like Lanting Preface. After 3 months, you should have a lot of feelings when you look back on your work.

On the whole, you wrote well. After all, this is a temporary assignment, so I won't mention the composition. You think you haven't made progress, but you have, because calligraphy is a very vulgar thing, and you can make progress if you think you are not good. With more practice and proficiency, the written words will be magical. Judging from this work, it is obvious that your strokes have stopped where they shouldn't.
