>>3174024Gelbooru, Danbooru, Pixiv. This isn't difficult, anon.
Pixiv is what you really want. A ton of artists have unfortunately moved to Twitter as well, though. So, maybe try looking up 白坂小梅 on Twitter and following any artists that pop up that you like. Just remember to save the :orig file when saving from Twitter.
Also, know that all of those sites have lewds, just in case you don't want that. So put rating:safe on Gelbooru. Danbooru doesn't allow multiple tags without paying, I think. And Pixiv requires an account to turn off posts tagged with R-18. Some posts that are R-18 can sometimes go untagged still.
