guardians of wind and ice

These two are the guadians of wind and ice, brittany (pigtails) is the guardian of wind and emmie (winking an eye) is the guardian of ice. Brittany is my apprentice (jake guardian of thunder) and emmie is helen's apprentice (guardian of shadow). Jake and Helen are rivals and want to use there apprentices to fight eachother. Except the two young girls become bestfriends. Jake then realizes what he is doing is wrong and the guardians should be using there powers to save the world rather than to fight his fellow guardians. These are characters from my story i am currently writing at the moment. lol this is just a few of them. i have a lot of problems with this picture. i personally feel i could have done better and i am very disappointed with it. especially brittany. im sorry this isnt my best quality but ill keep trying a comment or two would be greatly appreciated.
