Cool details
I like the huge variety of ideas you put into this, with an interesting style - and everything feels really well done, with attention paid to every detail of your designs. Because of this, one thing that bothered me, that sort of stuck out, is the way the strings in this movie vibrate when plucked. It's like they're made of wax, and just sort of wiggle once and fall back into place - I felt like they should vibrate more, more like a guitar or piano string, and so continue vibrating with a lesser and lesser amplitude, and never really completely stop, only continue diminishing. But yeah, that's all I have to recommend - and again, the fact that such a small detail is troubling says that your movie is excellent.
