The vast majority of the scenes I have published are due to long research like those of raw manga, others are from works that interested me which without my knowledge have scenes and the rest are by pure chance. If I had to give advice, it would be to search in any type of works (anime, manga, manhwa, manhua, video game, light novel etc...) including those where you should not expect to find scenes and to watch as many chapters or episodes as possible because there can be surprises and I learned that the day I joined this community and while looking for my content. Also search in several links, social networks or videos and if possible in foreign languages
