Is this any good? I had A sudden brust of expression?

This seems like an EXCELLENT monologue, not a poem. Not from the lack of stanza, but because of the language and wording itself. This would be a good drama piece for an upclose shot in a movie audition. (This is good, b/c writers shouldn't be limited). I would keep this version, and use it later for perhaps a published play, or monologue audition ideas. I would simplify it significantly if you wanted to organize and make it into a poem though.
