Comment/Critique my poem please?

Overall, I think its really good and it reminds me of a similar poem that I have written.... the 2 and 4th in the first stanza don't have the same beat as the others, but it works. When you used the word "thy" in the second stanza, it didn't quite fit in with the poem. You may want to change it to "your" or a different word that can replace it. My favorite stanzas are the second and fourth ones.... Keep up the good work :p
