Hiya
KKG:
looks good
Drawbacks:
"Members of this clan must also take the Hesitant (Specialization) trait."
You should add 'and it cannot be balanced with a positive' if you want it to be counted as a substantial drawback.
At the moment you have 1 active drawback, or two if you add in the above. I would like you to have 3 to counterbalance the fact that this clan starts with 4 elements. (Active drawbacks are things that take affect in battle and cannot be avoided via training).
Jutsu:
Jinton: Genkai Hakuri no Jutsu (Dust Release: Detachment of the Primitive World)
Give the size of the expanded shape, like how you did for the first jutsu. Also for the part where you say it can't be escaped without a jutsu of at least A rank, you can put that up to 'either an S rank offensive jutsu or an A rank defensive' to fit with the guidelines.
