Weird, I've heard of rag doll, but voodoo doll? thats unique. The ryhme is typical, and the two ideas has a form function thing...you know? anyways, It is a little creepy, but good. I enjoyed reading it. I can tell you put time into your poem.
I really liked the poem, until the very end. The ending just seemed a little bit rushed to me. Sort of like you didn't know where else to go, so you decided to finish it. But, other than the ending, the rest of the poem was excellent. Very unique way of explaining things, and setting the atmosphere. Nicely done.
