Like this? If I extend my Collars grouping down? My Shldr is further down the arm, more towards the elbow, so I don't think that has anything to do with it.

How will this, if at all, tie in with the joint parameters? Should I do both - extend the collar grouping and check my joint parameters?

EnglishBob,

When you say add polygons...do you mean take some of the faces under the armpits and subdivide them so there are more faces so to speak? (I'm using Wings3d) Yeah, my terminology stinks!
