Hello! I saw this video at AB and really enjoyed it. =) There was definitely a lot of work put into it and it shows. I especially loved all the character interactions and crossovers.
I won't talk about the technical aspects since I'm not an expert. (Heck, I just started to try some minimal masking myself, and hearing that you mask in Photoshop as well at the Avatar Music Video feedback confirms that yes, it must really be that hard and time-consuming. XP)
One thing I do want to say is that I wish you could've done a little more with the "Identify the Characters" portion by revealing some humorous answers (like calling them by character tropes/stereotypes or "Who cares?")? I was waiting for a clever punchline and it never came. Upon review I think I see what you were going for by pushing Naruto out of the way to show Kakashi, but it's so subtle it doesn't have as much impact as I was hoping for (though I've never seen Naruto so I can't speak for others who might understand the reference better)?
My only other complaint is that it ends too soon haha. Or rather abruptly. Again, it would've been great if there were one more conclusive classroom scene to wrap up the story - like everyone tired out (but happy) after the test and the teacher is actually shown handing back the grade. But it's a minor nitpick.
Overall, a very fun and engaging idea that deserved Best of Show. ^^ You did a great job with it, congrats!
