Good to know that graded readers can be useful! I might see if I can look up some of the publishers you suggest elsewhere. I'm so used to poor-quality English study materials that I tend to write them off.
("Spaced repetition" is a good point--I'm finding that, while not deliberately, longfic is also good for this! I'm thinking of a couple of those fics which are half again as long as they need to be because there's SO MUCH angst and miscommunication lol, meaning that, well, spaced repetition is what you get. ;) )

and glad you liked the photos <3
