Depends on what you’ll be posting. I haven’t really seen your work so I can’t say for sure, but if its erotic stuff, e621.net, luscious, ponibooru, derpibooru, rule34.paheal, inkbunny, or even blogger. (Don’t waste time with tumblr unless the majority of your work is thicc babes with tits, ass, and a dick every once in a while. Then you’ll rack up followers like no tomorrow.)
All kinds of places will host your work, but every site has some limiting factor to what you’re allowed to post.
If you want to post your artwork entirely for the sake of putting it out there as a gallery, make your own website. Then you get to make the rules. I believe that is much more freeing, and therefore more fulfilling. In fact, thats what I might be doing in 2019.
