3ds Max: Character Studio Tips

Hi, I've finally finished my first(crappy) character, and was trying to animate him via CS. It seems to be ok, fitting the biped etc and he moves not too bad, alot of things bulge and bend out of proportion ie his head turns his whole chest I was just wanting to know some general hints, tips rules for like Links, and the Overlaps etc, just to refine it a bit more.


Thanks
