The multiple facets of Raven's personality are having a "discussion" over who gets to be in control.  Looks like Dark Raven is winning.

If I remember correctly, the picture was inspired by an issue of the Teen Titans Go comic book.  The obvious appeal of this picture is that I got to draw Raven tied up three times in one picture.  I guess I got a little wild with the expressions.  It's also one of the early times I began experimenting with color modeling.  Some of it worked, some of it didn't.  That's the nature of experimentation.
