I'd say post it wherever you, personally, feel it should go. Myself, a lot of postwork and multiple 3D programs goes in Mixed Media, Poser with mild postwork goes into Poser, Poser with lots of postwork depends on what kind of mood I'm in. Don't worry, the gallery gestapo are usually too busy mistaking faeries for child porn to notice you. ::ducks bloody retribution:: For me, personally, it's kind of cool when I can get things together and looking good enough in Poser (or the renderer of choice) that I don't feel it needs postwork (except for a slight Gaussian blur I always use to take the edge off). On the other hand, it feels great when I can take an OK render image and make it look really good with post processing. What it gets down to most, in my book, is what you take joy in. If you hate post processing and want to be done once the render finishes, go for it. If you enjoy combining media to get the effect you want, great. Art without spirit is not.
