As a small time Freelance Graphic Designer, I get a lot less "design my original character" or "design my cover for my game/book/etc" and more "design my logo" and "design a t-shirt for my group/event", because honestly that's what I've marketed myself towards more.
But I always run into the same issue on sites like this where, with that being a majority of my time and work, what's worth posting on here or interesting to other users on the site? It's hard to share your work as an artist and grow when a lot of it is very "advertisement" based

As long as it's creative and well designed, it'll be good to post. As for the whole advertisement thing, you could send a PM to Tom Fulp and ask if it's okay.

Yeah, when I say advertisement I meant like logo and shirt design junk. I'd probably never post full fledged posters and fliers or whatever, I just don't think that matches with the site.
