As my D/G shipping sister, you are welcome to use any of them (though of course, crediting whoever appropriately, or they will come after you with pitchforks) if you like! :D

As for the Shalou ones, which are amazing in full size, they don't correspond to any story. Her notes basically said, "I felt like drawing this, so I did." Heehee. From her site, it appears she's actually normally a D/Hr fan. *puke* But I think D/G is growing on her. *crosses fingers*
