A random idea I had of giving Angel, well, angelic wings of light. I actually like the idea of giving Angel (and Devil for that matter) powers of sorts, to see if it would lead to more interesting avenues other then her looking sexy.
 
At first it was just a shape that was pure light with the emission shader, but it wasn’t very visually appealing, mostly because of how flat it looked. So I did some trial-and-error to try and make the effect look more interesting, and this is the result.
