While looking around on pixiv and adding bookmarks, I found out that good artists tend to have really good bookmarks of their own. This is how I find stuff like Anime Galactus destroying some planets. Also, things that users tag as “Futsukushii”, “Hisense”, and “Click Recommended” are usually great picks, and this one has all three.
