I was confused at first too, but it's a glowing pair of panties. Most likely belonging to an angel considering the theme the art is based on.

What is she holding, a used condom?

He is going to hell for what he did...wait a minute...

I love it

Ha i really love this at first when i saw the thumnail i thought this was going to be something about diablo looking like a female hehe, but this was still just as good, very welldone on the texture tones and even expressions you have here they show the emotion well, and you had a small joke here so that was good too and made for more enjoyment on this piece, so nice effort indeed, i look forward to more of your work soon,

I would really like to see you continue on this maybe more text bubbles for more story depth of it but regardless this was pretty amusing i thought.
