I liked this very much, the art and the lore information. I'm not familiar with legend, and your work makes me want to find out more.
I love the way you've drawn them, especially Snape. They're very different from HP canon, but recognizable too. I've always enjoyed HP ARs, and in the context of the legend, this perfectly fits the prompts and genre.
Plus, all the details: the misty appearance of forest background, the ravens, even the knots in the wood, all add so much to the feel.
Wonderful job - I have several favorites so far in the games, and this is definitely one of them.
