The Six Traits: Voice

What I think is one of the most important six traits is Voice.
I'm not talking about your character's voice (though that's still important) I'm talking about yours; the writer's voice.

Take this example from THE WIND IN THE WILLOWS by Kenneth Grahme;

Never in his life had he seen a river before--this sleek, sinuous, full-bodied animal, chasing and chuckling, gripping things with a gurgle and leaving them with a laugh, to fling itself on fresh playmates that shook themselves free, and were caught and held again. All was a-shake and a-shiver--glints and gleams and sparkles, rustle and swirl, chatter and bubble.

That's Kenneth Grahme's voice. I'm sure Stephanie Meyer's description, Hilari Bell's, J.K. Rowlings, and my description would be very different.
How would you describe it?

Voice: The distinctive style or manner of expression of an author or of a character in a book.
The American Heritage® Dictionary of the English Language, Fourth Edition

Your voice won't be distinct immediately. It takes time to 'discover' it. And the only way to find it is by writing as much as you can. That's the only way to be a better writer. The more you write, the more unique your voice will become.
I can't tell you what your voice is, much as I'd like to make things easier for you. Only you can figure that out.

But according to the Arizona rubric for the six traits, the highest score would need these elements:
The writer speaks directly to the reader in a way that is individual, compelling, and engaging. The writer crafts the writing with an awareness and respect for the audience and the purpose for writing.
