I've done a liiiiittle bit for my old comic that I worked on through highschool and college, but nothing very fancy and not meant to be shared. 
For my current comic... nononono LOL Since it's just a comic for fun and practice I committed the pseudo-sin of including a number of main characters with strong ties to real people, and as such wouldn't feel comfortable or particularly want to depict them like that >->;;;;; Granted there are plenty of OCs available too, but that's a Pandora's Box I'm cool with not opening lmao
