The repitition in this piece is much better than the other. A good example of proper repitition.
I'm really not a fan of nature poetry, but I didn't have a hard time trying to keep reading this, so kuddos to you.
I thought the first stanza was great. I love the line, "To quench the Earth's thirst". Really nice.
I didn't like the last line of the last stanza. I'm not sure why, it just didn't sound right to me. You're saying that the drop is leading, but then you also say that the others are following. I guess you're stating the same thing and it seems unnecessary. Try restating it somehow. Simply changing 'leading' to 'leaving' makes it sound better in my mind. Just a suggestion, though. : )
Again, punctuation at the endings of your lines would make it better.
