Just a few pointers, being a Work In Progress, you need to work as fast as possible, not trying to rush, posting a work in progress is usually not a great idea because for now it just takes up space.
I would say the history could do some fluffing, Appearance cannot simply be "look at avatar (e.g picture or google him." You need to state exactly what he looks like even if he is made up. You need to describe height, weight even, eye/hair color. Clothes he usually wears, his style of dressing.
Personality, simply can not be one line. Is he hyper at times, does it resort to violence quickly. What else does he do when alone, you need to elaborate.
Your weapon must say Key-blade, or type of weapon being Swords.
Elements are things such as Nothingness, Darkness, Water, Fire, etc. Tertiary is optional and useful. Though you lack experiance in it , it is useful.
I'd like to elaborate more on the fighting style, what does he do when the opportunity is near, does he strike to kill? Does he tire the enemy out and hope for victory.
