Personally, not a fan of the piercings. They just get in the way, and heck, who wants anything remotely pointy near themselves like that?
Not a fan of the limp either. Between crazy genetic splicing, healing chakra, Kyuubi regeneration, insane levels of skill with transplants, Forbidden Techniques that grant immortality and full body modification by the bucket load... Why the heck would he have to limp? Cursed weapon aside, but there really isn't much of that in-verse and you didn't go into detail. Puppetry technique to manipulate the limb via chakra links/threads etc?
Hope you continue, I'd like to see some life in his angels. Breaking them too much seems a waste.
