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.
