I love the rhythm of this poem. It moves along so smoothly and it has a steady beat...Except for the 3rd verse. The word "Myxomatosis" throws off the beat and it's pretty much lost until the 4th verse again.
I love your repetition like "O hallow, O hallow," "Thicker and Thicker," "Oh Shallow, Oh Shallow" and "Forget her, Forget her." I also like how you always capitalized after you repeat, such as both "Forget"s capitalized and the "O"s in "O hallow."
I also love your (once again, like in "Determinism") unorganized rhyme, such as "lest" and "jest" but also the more organized rhyming such as "weave" and "sleeve" (organized as in they're both at the end of their lines).
The arena Dragons Willow is speaking of (and the one I mentioned in my reply to "Determinism") is Gaia's Writing Arena. You can reach it by going to
