As for Alyson's joints and bending, I watch for differences between the whole body morphs and the individual body parts.  They should work together, and it's nice that P8 alerts you to differences, but the distortions I have seen in geometry can usually be fixed by reconciling differences there.

I see the usual knee geometry breaking in extreme bends, and her shoulders are really problematical, but, like 3Dream says, just be mindful of how you do it and the results are quite nice.

Here is another render of the poor, ugly girl.  I really don't know why I let her clutter up my runtime...
