My first character ever: Hermione rica

Name:Hermione Rica
Age:13
Gender:Female
Eyes:Hazel
Hair: Between Brown and Black, ear length
Height:5"7'
Body Type: not really skinny but not fat either so in-between
Skin Color: Pale with a bit of a tan
God Parent:Eirere the goddess of peace
Mortal Parent: Christopher Rica
Country of Origin: Born in Hungary but at 1 month of age moved to Canada
Pets: none, allergic to most animals
Talents: public speaking, singing, and debating
Weapon**: Her voice.
Flaws: She has a condition that makes her weak, such as unable to run for longer than 10 seconds, she sometimes has trouble walking. Fortunately with her voice as her weapon she is one of the most powerful demigods of the age for the gift is extremely rare.
Powers(must relate to god parent; optional): When trouble arises Hermione is able to bring peace, she is able to create relationships with with everyone. Unfortunately her power cannot beat Gods or Titans, she can only weaken them. Also Hermione can control anything that is at peace like still water or a gentle breeze or even her opponents
Life Before CHB*: Hermione never suspected that she was a demigod, she lived a normal life, well as normal as someone with a unknown contition can have. Her grades were good, she had a couple close friends and she was having a good life, at least until she moved schools and found out that her principal was a cyclops and her enemy who always bullied her was a satyr.
RP Example*:" Urrrr" screamed Mr. Credome as he flipped the desk from which he had sat behind. Pencils flew everywhere! Kiana said " Hermione run!"." I can't run!" I replied. "Try" so as fast as I could I ran, Kiana raced ahead of me and said "Follow me!" Kiana ran out of the school and in to the highway full of cars. She ran up the high way 5 cars then 2 lanes in where she stopped, looked around, opened the trunk and jumped in. Hermione was on Kiana's tail so she didnt have time to hesitate as she slipped in to the trunk. Hermione saw a hand reach toward the trunk lid, started to pull it down but she didn't notice the trunk lid close because Hermione saw the world begin to spin and the world around her went dark...
Any notes about your characters:

How is her voice a weapon?
Add another flaw.
You can't really just say that she is one of the most powerful demigods..
For her powers: How is she able to bring peace? How many times a day can she do this? how long does the peace last? Being able to create relationships with everyone isnt a power(unless there is something magical about the way she does it? If so please explain more) How can she control anything that is at peace?
Please add 3 more sentences to Life before CHB

We definitely wouldn't let her control things that are at peace -- we only let kids of Eirene give off a peaceful atmosphere or calm people down.

You say only children of Eirere can calm people down or give off a peaceful atmosphere but I put down hermione's god parent as Eirere sooo...

God Parent:Eirere the goddess of peace <-- Actually you said Eirere. I did some research and I'm afraid you have the wrong name. Replace the last r with an n and you've got the correct name of Eirene.

When trouble arises Hermione is able to bring peace, she is able to create relationships with with everyone. <-- to me, this is more of a talent. Sorta like being the social hub of everything or something like that.

I believe you've misinterpreted what I've said, Number -- I was merely listing powers for a child of Eirene, not implying your character isn't a child of Eirene.

I suggest you remove her first power and add another flaw to your form.
