Please share your thoughts! :)

Okay so I'm working on a new idea of mine, it came to mind when I was listening to the song ET from Katy Perry while reading Supernatural Fanfics(I know, weird combination) xD.

Anyways, my story is about a girl, Savannah(18 years old), who is a very shy and quiet girl. She feels like she's being judged by everyone around her and blames it on her lowsy people skills. When she was a freshman, she started to draw a girl with pink hair and a pink eye color. She named her; Aimee.
Savannah's father is an astrophysicist and has discovered a moonstone with some weird looking bacteria. He is convinced he can make the moonstone function like a human being with the right means. Savannah leaves her sketchbook(with inside, the whole story of Aimee including drawings, conversations, characteristics etc. by accident in her father's lab and her father decides to bring Aimee to life.

So that's my main plot. But here's something in addition.

The story will end with Savannah dying of old age, and Aimee sitting at her bedside. Aimee hasn't aged because she isn't designed on getting older. Therefore, Savannah asks Aimee to move on with her life and help more girls like her. Aimee listens to Savannah and after her death, she leaves. On her trip, she meets Blaire; a twenty-one years old girl with troubles at work.

So? What do you think? :)
