Back topology... I think the shoulder blade shape is OK, would like some feedback.  I went to a much simpler back topo and I think I'm going to leave it like this and move on to arms and legs.  I could do this with a lot fewer polys but I don't think that would work all that well for animation.

I managed to get a nice clean loop going all the way around the whole rib cage, which I think will make a "breathe in" animation very practical (select inside the loop and scale).  We'll see I guess when I get to that point.
