Hey there, Azi! Whilst this is a good start to your character, her personality needs a few more sentences, and it may help to expand other sections as well. For her personality, you may want to describe her likes, dislikes and tastes - what can she absolutely not stand? You say she's a bookworm - what's her favourite genre? Just a couple of suggestions, if you get my drift. Also, for her fatal flaw, you may want to say how it is fatal. She thinks she is always right, but how could this lead to a near-death experience? Plus, it may help to run your application through Microsoft Word. The grammar and spelling aren't exactly up to scratch, although it's not My Immortal bad. A good start though, she just needs a little bit of work.
