You may not have a child of a big three person. Did you read the rules?
Anyways, your focused on the minor important details, as I see. Blue eyes and scars are not making me visual picture of him. Hair color and style? Height and weight? Skin color? How does he dress? Any freckles? Etc.
For personality, nice is a good trait. How do you get on his good/bad side, though? How is he on his bad side? Friendly? Moody? Etc.
WTNoodles is a WaterWave? Please explain!
As for talents, swimming is not all that he's good at. You're not even supposed to have a child of Poseidon, anyways.
Your first issue, overall, is that you didn't read the rules :3
The main one is that this profile is not detailed.
That's what I've got to say [:
