I have compared your modification and my score. First thing is that your's is not written in Concert pitch, forgot to click away that.
Now, beginning from measure I:
You changed the Flute II by inserting two 1/4 notes, I guess that is to give the piece a smoother introduction to the motif? You changed the dynamic to p instead of pp
In measure II:
You take away the pause in Flute II and add a 1/2 note, so that it will become a triad.
In measure III: You change 1/2 notes so that they overlap one another.
There is added dynamics for Bassoon I, mf to f. So that it doesn't sound to weak compared to the bassoon II playing f in the following measures.
IV: Transpose the Flute II one octave, the flute too weak I presume (I was actually thinking of having and enclosure, but then I realized that it should have been usage of Flutes and Clarinet instead of Flutes and Oboes, or does that not matter? Eitherway, the flutes to weak.)
VI
Dynamics added, f in all instruments playing as wells ad a diminuendo, this is so that the listener gets reassured that the climax has passed and it is to lead into another part.
The following measures you have added p to all play instruments, so that a contrast is created?
I hope I found most changes
