Your appearance description is much too short as well as the personality section. Take a look at other CS's and compare it to yours.

Oh okay, it's a one hit kill if you put it in someones mouth. That's a no, there's no 1 hit kills on jutsu or weaponry.

Understandable, working with poisons is a process of fairness between useless and OP. 'In someones mouth', tends to mean down into the lungs and the like but then again that really bangs on forcing someone to drown/waterboarding in the middle of combat. So how about 'impairs speech' which can be just as dangerous when it inhibits calling out attacks or issuing orders? Treating it like a powerful on-contact Novocaine. 

Originally the venom is based off of the blue ringed octopus https://en.wikipedia.org/wiki/Blue-ringed_octopus and shukoku is such a beast to milk the venom from, but that is intent and information, not fighting a ruling.

Also I am not sure on the KG. It seems okay, but then as a water shinobi you can always just make water come out of the ground and convert that to chakra. That basically gives you infinite chakra.. so.. you need to clarify a bit.

While that was a bit of the point was to be like an aquatic gara who had infinite sand/dirt to work with, how about all water jutsu uses half the chakra to cost and maintain if sacrificing one water technique to fuel the next technique. Such as the example of converting the mist technique to water prison only costs half as much jutsu because he is already had the chakra manipulated water to draw from. But the first time he 'cold casts' a technique, it costs the same starting chakra as any others.
