Very few fan artists are putting up their fan art as individual works. They are making galleries on their bio pages and usually if the fic is part of a challenge it will go there as well. Commentary on the fanart goes wherever the art is located. But to many fans, making page for your own fanwork can seem...presumptuous.

To use my fanvids as an example - I have broken out a few fanvids that have received commentary as stand-alone pages. Vids where I don't have a lot to say or haven't received a lot feedback are still sitting on my user page. But if someone were to make a page for any of my fanvids no matter how much or little commentary it had, I'd be thrilled.

Artists are more proprietary about their work and often don't like it when someone else makes a fanpage about their work or even adds it to the challenge it was designed for or includes it on the zine page where it was first published. Which shows that within fanworks, there is a wide diversity of how fans feel about others talking about their fanworks. Or to put it another way, in the context of a story, podfic or a vid we are usually *talking* about the work. When talking about fan art, you often show and tell both.
