Fantastic!
The thing that stood out here among the rest is your graphical style. I am really
impressed by the pixelated style pulled of so well. Additionally, the color palette choice, highlights and shades were all top notch. I also noticed a lot of vibrating color schemes, which made it stand out more. Lastly regarding graphics, your designs were very well executed.
I like the imagery and placement of things in your movie - such as the windmill, the lights, and earth and stuff. The backgrounds were also drawn nicely.
This is all very visually pleasing, but the only thing that pulls away from it is the concept or story behind the whole thing. I don't feel like I understand what relation the song has to the movie, as well as I don't think the elements were universal enough to understand what it was about without being able to speak the language the song was in (which was japanese or something right?). But, your summary below the movie clears everything up, so all is well.
Regardless, I really like this, so I am giving you a 9. Good work!
Can't wait to see more stuff from you :) :)
