The visuals are spectacular.
Excellent. I have enjoyed this video very much. : )
It was very different and creative, both in visual and music integration.
The story-telling was needless to say, awe-inspiring.
Scene1- 世界 / The World
Scene2- 最初 / Opening
Scene3- 殿村望都 / Moto Tonomura
Scene4- 死前 / Last Day
Scene5- 最後 / Conclusion
Scene4 sounds iffy as 死前 is not a real word, like you stated.
最後の日 would translate last day, but I'm assuming you wanted to keep the scene titles within a word, and also with the take that 最後の日 would sound repetitive with the Scene5 title card, "最後.”
You may want to use alternate words for Scenes 2 and 5, and/or replace Scene 4 with something else.
Pairings for opening/conclusion that I would go with:
For scene 3 Last day:
死の前日 ・ The day before death
最後の日 ・ The last day
I would go with whatever pairings you feel comfortable with. Or something. |-:
Anyways, you have created a masterpiece that is top-notch art. : )
Brilliant work, trythil!
