Clavicles, oh my!

I have this fascination with clavicles, aka "collarbones".  I broke one of mine when I was around two years of age, falling off of a bed, or a chair, or something like that - must have hit my head pretty hard on that one too.  Anyway, I was fooling around with some closeups and thought I'd share my two favorites.  Hopefully you can tell what they are - I think detailed body portraits are just beautiful.  Hope you are having a wonderful evening!
