"'Tis my place I like to be
Just the earth and ground and me."

= First, I don't think you should start this with "'tis", because you haven't told us anything about this place yet. "It is" might sound better. The second line shouldn't have two "and"'s -- "just the earth, the ground, and me."

"Where water flows and falls
Down a cascade of rocky walls"

= Simple, but I like it. However, I feel like the flow is off. "Where water flows and falls" isn't smooth. To be honest, I don't know what I would change to make it better, though.

"Where sun shines upon my skin
The best place I have ever been"

= Again, it's pretty simple. I think this piece would be better if you used a it more diverse vocabulary. I'm guilty of using small, simple words, actually. Haha.

"Is my rich river up in the clouds
Away from people away from crowds"

= I really don't like how this starts with "is". [**For an explanation, look at the bottom of this comment. :)] In the second line, you should have a comma after "people".

"Just a place I like to be
Just a place, a place for me."

= Nice ending. Brings the piece to a nice, even close. Good job.

**Throughout the poem, I noticed each line starts with a capital letter. I don't think they all should. I think every OTHER line should, though. This is the reason I don't like the line beginning with "is".

Four out of five. [4/5]
