Gah!  You're a sculptor!    I am so jealous.  I've always wanted to sculpt but my fingers dislocate so badly that it never works out.  It's great that you're able to!  I mostly just draw--India ink and alcohol markers primarily.  And I watercolour.    I adore clavicle bones.  They're some of my favourite things to draw-- getting the shading and contouring just right is so satisfying.  I always notice a beautiful set of clavicles on someone.    And the fact that whales are now painting on clavicles just sort of staggered me when I first learned about it.  The stupid things they'll do to appear thin while whalesinging about HAES is ridiculous.
