Do you agree with my teacher's comments on this poem I wrote?

Good rhyme scheme and couplet at the end. I believe it was because of some grammatical errors such as "preamble to next". That kind of sounds weird. Also, why is power like that. But over, very good. She also might've done that just because if she gave u "amazing" on everything, you might have not tried as hard on the rest. Many teachers do that
