Every artist likes exposure. That is natural and the internet gives access to the biggest audience on earth, but where to put your work?
I will start with Pixiv. It is a Japanese website that slowly has adapted to English speaking artists. It has a huge user base and that makes it ideal to display your art. But since it is a Japanese site, censorship is required. Genitalia has to be pixilized or in other way removed. But in most cases, it is just needed on the front pictures that appears on most parts of the website. Allowing you to post uncensored versions as additional pictures in the same set.
