Its-A-Multiverse contest entry! Let's grade it with the rubric!

Title - 10/10 points
The title is there!
Point Range: 5/5 points for correct spelling, 5/5 points for it being there.

Author - 5/5 points
The author is there!

Cat - 5/5 points
The cat is there!
Point Range: 3/3 points for correct pelt color, 2/2 points for correct eye color.

Your Name - 5/5 points
Your name is there, and also less noticeable. Though it's very hard to read, so next time make it a little bigger so the human eye can read it.
Point Range: 3/3 points for having your username on the cover, 2/2 points for making it less noticeable.

Visually Pleasing - 15/20 points
The picture is rather blurry, but compliments the theme of the book very well (dark/mysterious). The cat looks nice, but perhaps a little old for an apprentice (remember that we are speaking about a young apprentice named Berrypaw in this book). I would've liked to have seen a little more consistency in the placement of words, and a little less space between 'Fallen' and 'Leaf'. I like how the font looks the same but isn't (if you observe closely), though I would've liked to see at least two fonts that contrast against each other. Other than these things, this cover is pleasing to look at!
Point Range: 15/20 points for being visually pleasing!

Creativity - 10/15 points
Not utterly creative, though I did like the way you used the tree to separate the name of the book and the quote on different sides of the cover!
Point Range: 5/5 points for not looking like a warriors cover, 5/10 points for utter creativity!

Color Consistency - 20/20 points
The colors are consistent!
Point Range: 20/20 points for good color consistency.

Neatness - 12/20 points
This is pretty neat, although the wording and spacing could've been a bit better.
Point Range: 5/5 points for fitting the Wattpad format, 1/5 points for visually pleasing format of words, 1/5 points for having a good image (not blurry, respectful of the theme), 5/5 points for having all things on the cover.

Warriors - 5/5 points
It has the word Warriors on it!
Point Range: 5/5 points for having the word Warriors on the cover.

Late or Not Late - 5/5 points
This wasn't late ;3
Point Range: 5/5 points for having the cover turned in on time.
