Thank you, Jitter and Grey, for your advice! It really helps me to see little things I didn't pick up on after hours of working on the same footage. ^^"
I agree, it's too fast on certain parts, I will work on that, promise!
As for the relation between lyrics and video, there isn't really one. I did look up the lyrics (because I couldn't make them out either), and they're pretty repetitive. The fact that the official music video for Midnight City doesn't strictly tie in with the lyrics either shows they're not really that important compared to the melody that (in my opinion) is what is truly memorable about this song. Still, I tried to match some of the lyrics to the pictures though, like Lalli's eyes seeming to light up when the lyrics say "The night city grows, look and see her eyes, they glow"; or panels of Sleipnope and the ghosts looming around to the lyrics "waiting for the right time"... but that's about it. ^^"
But like Grey said, my intention was more to make a sort of "trailer" for adventure one, rather than to tell a story with the song I chose. I will definitely try to do that next time though, if I find the right song. ^^"
