I enjoyed this peice a lot. Unlike Gadfly, I got a powerful image of looking through a keyhole and seeinga beautiful white light [from 'prism'], the 'key' being a realization of some sort, the sort being how you intepret the poem, kind of a look back on something you've done wrong and wish to change [from 'prison']. It was Nice. One thing I'd advice is varying your punctuation. for example: "Along the road and in exile There were eyes watching.
Green and blue - Cold and cruel.
Narrow glare. Solemn stare.
I know one day I will return there.
[Prison song. Prisms raw in loose sermons: I have seen the key.]"
Only a couple of changes, but that's just a suggestion on how I would have executed it. Feel free not to take it up. A good write Regards ~ Uriel
