From my understanding of your choice: you have one too many proficiencies. For a Chunin, you have three options, I thought you were doing opt 1 so feel free to correct me if that's the case:
Option 1. Begin with taijutsu, shurikenjutsu*, stealth, and two additional proficiencies all at apprentice level.
I would recommend to fit your build the best to remove the elemental release so that you can add them later to unlock the Shakuton, or perhaps take it in a different direction with the tai-oriented initial build you have.
In terms of the history honestly it was a great read: but I'll need to get back to you at your character's position as a "central figure" in the site history (Kazekage's daughter's husband to be, interference/interactions with Shinko) but should hopefully have an answer for you today (19/09/2021)
Hi, the history is approved. Kyujutsu needs to be adjusted to remove use of the wind chakra until the proficiency is acquired and then you should be good to go.
