it's where my demons hide

So guys... I need help. Do any of you like and or read poems? If so, I could really use help. I am in speech club in my High School (YAY SPEECHIES!!) and I am doing the easiest thing there is to do: Poetry. 
The thing is, it has to be 6-8 minutes long, and so far mine is only 4. My topic is demons because right before Speech practice I have global intolerance, which is the most depressing class ever, so I am usually quite upset when I'm in the club. I just need one or two more poems, not to long and not to short, and they can't rhyme. My coach said they have to be by a well known poet. To give you an idea of what I am looking for, below I have enclosed my other poems. Thanks in advance!
