Welcome! Oh, yeah, you have a lot in common! Quite a lot of us are storytellers, either first with words, wanting graphical settings, or primarily with graphics, then putting words down to explain the world. Even if you want to do your own brushes it wouldn't hurt to play around with premade ones, to get a feel for how you're likely to use yours.
And we'd love to take a look at your prior work. Don't even have to scan stuff in "properly" - photos will work if you can't scan. Y'see, while the site is digital, not all of US are digital artists.
