April 2008 Writer of the Month
Be aware that only 2 and three are true haiku's, in the traditional sense. It's fine to take aspects of haiku's and use them as you please, just be aware that you're not writing a traditional haiku.
I liked the third best, in its simple imagery.
Again, you sometimes miss a key aspect of the craft of Limericks; the twist in the end, the last line should make the audience go "ooh", "aah", or "whoooooo".
No time for more critique now. More soon.
