Yes, I like!  The plot thickens, and Riddle is already showing his tyrannical personality.  Although you initially describe everyone by the color of their eyes and hair (and they're all a little too glam for my taste), you make their differing personalities come through in the dialogue, so it doesn't seem so much like an Anime adventure.

  As a Riddle-McGonagall addict, I should remind you that this is happening back in the 1940s, so some of the slang you use is not quite authentic, but who cares about that?  TR's last year at Hogwarts is certainly a good choice for a story.  I look forward to more.
