Wow...
I am impressed in a way. When I first read this piece it seemed too simple to me but during the second reading I started to see true depth of every line. Amazing poem, remarkable and certainly one of the most original pieces I've read in a while.
I think that this is excellently written from the first to the last line.

I love this. I could imagine this sound in my mind, getting louder and louder. So creative.
The ending line is also very effective, it sums up whole piece greatly.
