"Even when my corpse is out of breathe" should be "breath", "breathe" is the verb. Technically speaking, I thought the rhyming was pretty good, including the slant rhyme of blood/understood.

What freaked me out most about this poem is the last stanza, specifically the lines:
"Bury me with this smile
The smile i carved myself"
For some reason I get the creepiest (sp?) image when I read those lines. Very interesting work.
