Pitty Whiskers

Some days ago I was drawing wirh my creative pen tablet and decided to make some sketches of expressions.  Life of Pitty Whiskers is an old story I created with my sister. Pitty and her older brother Max are antropomorphic cats that live in an alternate world where cats developed inteligence instead of humans. After destroying their house in a fight, their parents decided that they should learn how to be siblings. Pretty much the story is about them getting closer as siblings and turning to be best friends, but it won't be easy. 
It's a cute story , funny and with a lot of hearth about growing up and the importance of a sibling. 
Pitty is the deutragonist but the one that gets most of the spotlight. Why? Well this 10 year old kitty may seem cute but she is much more than that. You can call her crazy and she will agree, she is extremely inteligent and creative and sometimes can be a little bit evil, but in the end Pitty is a little kitty that has a lot to learn about life.  

Some fast drawing I made of her in photoshop. What do you think?
