I think that if Raven would willingly hug anyone, it would probably be her mother, at least in a moment of weakness. I had been compelled to draw this after, earlier in May, I'd accidentally stumbled on a titans site that had screenshots of "The Prophecy" that had then been aired in Canada.
Mostly I think I just wanted to draw Arella, because I noticed right away the facial structure was different than what I was used to. It gave me an excuse to draw a very slender face.
