No offense, but there's no point to Danbooru if no one uses the information. Pictures like this are generally not in a collection because they come straight from the artist's website- the only place you'll find more is by going to their homepage (the "Source:" link under "Statistics") or clicking on the red artist tag ("eroquis") to see more from the artist in the Danbooru database.
Look at it this way: if you learn how to do this now, you won't have to ask "where this is from or what this is from or where i can get it" anymore. You can just get it.
