I was wondering how I could improve the visualization of these items. Any suggestion?

the other two models look ok, but the bear seems to have some weird shading/reflection issues going on there? can you see that yourself? The refelction goes black if your looking down on it?

Just trying to figure out why that could be, umm

seems to relate to a post processing setting, not sure but it looks like your using AO, did you try fiddle with the AO bias ?
