Torso-astic Armor

I thought the character looked a little bare and unprotected, this species has, as I've stated before, a tribal warrior culture and are very agile and good fighters. Now a specialized and bare outfit like the character is wearing now is ok for a stealthy assassin unit or something similar, but what I am going for is the soldiers outfit that would be the standard for this species and I would then want at least some armor on him.

It is fairly low poly (for a sculpt) and low detail, but the intention is for the armor to consist of some creatures bones to protect from slashes and I will want something hard in between them that at the same time wouldn't restrict movement. And I will also need to find a way to make the bones not seem too rigid so that would allow movement as well.
