Sorry for the delay!
1. Alright, noted.
2. Sounds good. So just for fun. Alright.
3. As for the personality thing, it was more of a comment towards the "like most of her classmates/hunters/huntress" they're terrified of growing attached to others. Hard generalization isn't really good. Still, approved.
4. Semblance looks better now. Was concerned that having a crushing force all around someone was akin to telekinesis at that point. So it takes a few seconds to start rather than a gradual increase of pressure. Makes sense for a disorienting semblance. Looks good.
5. Combat behavior approved.
6. Weapon approved. After some more research, it seems like a flechette round can be used for longer range but the light weight of the ammo makes it difficult due to the effect of wind. That plus the multiple barrels your character's weapon has makes it less likely to be an effective sniper rifle, but since you're ok with it being short to mid range;
Approved 1/2
