Before I forget to post, here are the redo drawing of the main character and the bone skinny bunny. Since interface, we were told that the drawings were conflicted by there style.

For the character, made her more cartoon-ish.

Made bone's similar to the other two. Making him standing up on two legs instead of four, but still keeping his tiny figure.
