Create a character (Base)

Okay first: Thank you all so much for trying this with me! I'm really happy you all seem interested in this. >_<

So we are female (2to3) and around 16 ((13+16+18+18+15)/5=16) 

I decided to sketch three bases as how the body of the character could look like (it probably will change though features and story decisions later on) and also what kind of style I would use. (Of course the pose can also change)

What I want you to do is choose one of them and tell me which one you would prefer. Of course you also can add what you would change (but remember I need reason (something like she is chubby because ...)) 

So the question for this week is:
What style/body should we use?
What is she doing? (Like is she going to school or does she work? Or is she maybe a magical girl or some kind of superhero? What do you think?)
