Low-key, I like different thumbnails. I’ve seen some people do some really cute and creative things, and I think it’s a nice touch! Not necessary, but fun nonetheless~
As for my own work, I designed my thumbnail icon with a “vinyl cover/sleeve” idea in mind (with some, uh, liberties lol) just for laughs, but I had so much fun making it that now I’m debating on making more with different colors/“characters” for each new arc, lmao. idk if anyone would really notice/care, but adasjkd; I like playing around in photoshop too much to stop
