>>3673752Zerochan is a good starting place because most of the stuff there is sourced and well tagged. You can use it to find the Pixiv and Twitter accounts of the artists, and collect more art that way.
Searching the Pixiv tags alone can be a little overwhelming since there is so much content. A lot of artists will use the "??1000users??" tag (Genshin Impact 1000+ bookmarks), which can help you sort through the trash, but you're going to run into a lot of horny Ganyus and Monas that way. (You can also modify that tag to be 500, 5000, 10000, etc.). A lot of people won't tag the characters in the image sets either, so it takes a lot of sifting.
Twitter has the most artists, and a lot of KOR and CN artists can only be found there, but it's the hardest to navigate. It doesn't have a proper tagging system, the only way to see a artist's past work is to scroll backwards through their timeline, and the image ids can't be used to find the sources. The best way to find artists is to identify a few you like on Pixiv that have twitter accounts, follow them, see who they follow, and see who twitter recommends that you follow after that. The best accounts to follow are ones that retweet other artist's works. After you have started following enough of them your feed will be full of retweets and recommendations.
Twitter also compresses the hell out of images. If an artist you find on twitter has other places they upload their work, almost any of them will be hosted in better quality. With the exception of Weibo. Weibo looks like it puts its images through a fucking meat grinder. It also hates foreigners and doesn't let you view anything more than a few months back without an account so it's mostly a no-go. Lofter is similar in that regard, but doesn't mangle the images and if you are quick with right-clicking you can get past their popups.
