Tips for pixiv: Search the character's name both in kanji and normal letters and look at the recommended art below what you find, search their popular ship tags too. Sometimes I have to search for "Hashimada" even though I hate it, because the posts are not tagged with anything else, and there might be a solo Rikudo Madara picture in there!

Pinterest - the webiste is absolute cancer, but it is good for finding deleted art. Crazy fangirls save everything on pinterest and it will stay there even after the original is deleted. I've found so many new rare Madara pictures there!
But the art on pinterest might many times be low quality and that is where the magic of reverse searching comes to play! Download the browser extension from Saucenao, it lets you image search 4 services with one click! I like Google the most though. It gives you more similar images and some of them can be new ones again!
More sites: Tumblr (sometimes you can find good art there, but it is like finding good things in a trashcan), VK (russian facebook, similar to pinterest, many deleted arts as well, but you need an account to search tags), Twitter (my favorite, follow the artist you like and wait for new art! Check who the user is following to find more art you like (that happens to be untagged)
I hope I explained it well, I suck at explaining a lot though so if you have any questions please shoot!
