Cyber Mercenary Character - Low-poly 3D Model Low-poly 3D model

Overall positive 3d Model. There are a few issues, please update. The Rig model with bones isn't connected naturally. I have to move each bone on its own, instead of moving a thigh and it moves naturally, or the hip, etc. The rotations aren't natural, again a bone issue where I have to rotate pieces individually. No bone constraints, no limitations at all on anything. Some armor pieces are too far apart from the rig, the back top plate is separated from the rig to where you can see it, and if you add animation of lowering/rising arms it pops up higher. Would have liked some constraints to limit lofty clipping.
