There were some grammatical mistakes that I spotted: a few commas missed, a few comma splices, nothing major.

This was really nice, though; I really liked it. The last lines really stuck with me:
"Face upturned to the sky / She’s free / A smudge of gold in a world of green."

I, personally, love trees. There is no lie in that fact - I actually was considering writing my informational speech for school (which has to be four to five minutes long) about trees. I might need to get to work on that as it's due tomorrow, but anyway...

This really was a nice piece - there was some nice imagery and such.
