Wind

[Lizzie]

Acorns collecting -- I like collecting better than reflecting here, and adding reflecting in the next line works much better. Seems like the main idea is acorns huddling up to protect against inclement weather -- it's adorable and original. Makes you care about the acorns. 
Reflecting tree branch dances -- keeps it from being too sad
together apart -- I have to be honest: this sounds like it's trying too hard to be clever. The juxtaposition isn't particularly fresh or surprising. 

I much prefer the last line in the first draft. Even though the phrase is commonplace, it was used in an original way. 

Makes me pine for fall..... (since oak for fall isn't really a thing)
