The moonlight on dark waters... Took the words right out of my mouth!
Folksong? A folksong is... is what? I know "folk" and "song"... I'm very short-knowledge on these types of stuffs, but school things are easy (since I'm still in school... oh.h.h), so I don't know what to say. It mainly is YOUR opinion, anyway.
Critiques: As far as I can tell spelling, grammar and any other concerns checked out. Mostly because it's a poem. ^_^
I really, really liked the rhythm of this poem. I'm not sure if this is the way you meant it to be, but it was quick and... indescribable. In any case I loved it. Very smooth though I thought it stacatto. Keep writing!
It sounds like a folk song to me, and I really like the images. There's not a break to the rhythm, and I could easily hear the voices singing in my head. Well done!
