Oooh, how sweet! Please tell me that's a halo glowing around Aziraphale's head, because that's gorgeous. Also, I just can't get enough of your Crowley. He looks so suave and charming (even when he's in a situation of nervousness like this), and I love him.
Wow, your Aziraphale is yummy! A bit chubby (which I love for his character) but with such delectably handsome features. The fact he has a far more canny expression than Crowley, who almost looks innocent, is awesome Plus a halo, and a hint of wings for them both? I'm in love.
I applaud the absolutely wonderful use of traditional media. And the fact you've drawn in black & white, because so few people do.
