My daily doodle the past few days has been trying to figure out how to finish my tattoo.

This is the outline I’m working with.  The Taurus circle is already on my back, so I’m adding a larger piece that spans my shoulders.  I was having trouble with what to fill the larger piece with…would it be solid, tribal, henna pattern?  Now I want this piece to be more than just an optical illusion that broadens my back.
After dozens of designs, I think I’ve narrowed it down to a final concept:
Celestial
Encircling the Taurus ring, the larger ring will be filled with the waxing/waning moon cycle (for growth, rebirth) and the wings contain two personally-significant constellations (Orion and Ursus Major) with numbered stars for the important people of my life.  
I can’t wait to get home and draw this out in larger detail.
