Design a Cool Locker Character for a Journal Cover for Kids

My Locker Buddy

we are a innovative company that develops educational, fun and innovative children's products and holistic living.

I need a cool locker created that will be used as a journal cover for kids ages 6 to 12 (1 girl &1 boy) - just the front outside door for now - please submit 1 girl door and 1 boy door.  The door should say WOW to the kids and really make them want to open it up and write in it.  The locker will be their "BUDDY".

Please also include 2 face "add-on parts like eyes or glasses or mouth" per locker so kids can customize the locker character by adding these face parts on the locker - which will either be magnets or stickers - see attached pictures of the cool drinks. 

Changing the locker per gender could be as simple as changing the locker door colour and maybe 2 additional gender add-on parts.  

The finished product will be a book approximately 7 inches wide by about 15 inches in height by about 1 inch in deep.

Most of all I want kids to connect to the Locker character they will customize. Nothing too juvenile - it has to be FUN FUN FUN and FRIENDLY!

I have attached images that I really like the look of.

I only want a the locker character designed so when the kids open the journal, it is as if they are opening the locker.
