Character Design - Jack

For Jack I want a character that is heroic but naive, mid to late teens. Here are a few idea sketches.


First sketch: this is a possibility for Jack, he has a certain charm which could be useful for the character.










Second sketch: this character does not look mature enough to be Jack, this design was modeled on the idea of Disney's Aladdin








Third sketch: this is very close what i imagined Jack to look like. This designed was modeled on Disney's Jim, from Treasure Planet.
