Icy Fist[Tsumetai Genkotsu]
Type: Taijutsu/Ice Release
Background: Long ago a lone member of the Yuki clan was very obsessed with taijutsu, but his parents wanted him to study ice release and forbade him from learning taijutsu. Several years later in an inner village tourney the member dominated the finals of the tourney through the usage of taijutsu and ice technqiues combined together into one, he was then acknowledged by his parents.
Description on the Abilities and Inner Workings of the Style: The idea of the fighting style is quite basic yet very effective. It is simply based on incorprating ice release into taijutsu. For example a simple jab with the hand will have a spiked ice spike on it to increase lethality the usages of this art are only limited to the imagination of the user and their knowledge of taijutsu.
Additional effects and Restrictions:
-Must be member of Yuki Clan
-Must be Kage rank and above.
-Must have training in taijutsu.
You're going to have to describe this a bit more. As it is now, it's just coating different parts of your body with ice and then attacking with them, which doesn't qualify as a CFS.
