Fictional Stained Glass Windows (that people actually made):
Stained Glass of Ganon from the Hidden Chamber of the Master Sword (The Legend of Zelda: Wind Waker)
Princess Peach Castle Window (Super Mario Odyssey): One or Two. The situation here is odd, because, the way I see it, One is cleaner, and deals with the body proportions a bit better, and so feels more accurate. However, Two also meets more of the details. In the original stained glass (seen here), you can tell that Peach has five fingers, because–though her hands are clasped–they can be seen up to the first knuckle. This is true in Two. The little circles setting the jewels in her crown in place (I’m sure a jeweler would know the word), have a tiny bit more detail than they should on One. Peach’s shoulder strip of fabric on her sleeve (jargon that I again, don’t know) is meant to be lighter, and Two follows this, as well. I would also say the color accuracy for the lighter tones on the roses is closer with Two. (There is arguably a subtle color difference between the panels in the last row of her dress in the original, and the recreations handle this differently, but since this could be due to shadow in the game, I can’t say which is right.) Again, the pieces in One fit better, many in Two are curved where they shouldn’t be in an effort to fit into their correct places. This makes One look more authentic and like it could be the real window, however, based on technical details, Two is correct more times. And then I found a third contender. Three, like One, is inaccurate on the knuckles, but it is accurate on the shoulder stripe, like Two. This should put it a step above One. However, I do like that One has somewhat more accurate proportions vibe-wise (for example it has slightly bigger jewels, which give it a more cartoon-y look.)
So, I thought that was done with. Then I realized that a N64 Mario game has a separate, nearly identical–but for the purposes of this list, very different!–window. So I went through many more. Stained Glass Geek is the main replicator here, with many following their pattern (though there are a few unrelated iterations.)
+ Bonus: There were some others that don't really count, even though they are definitely stained glass of fictional stained glass, since they're tiny and explicitly designed not to be used as windows, like these: Wind Waker Sword Glass, Other Sword, Bow, Sages, Sword and Shield.
