i really liked the concept which combines aoi bungaku stories through the one with the writer. this idea is quite fresh.
therefore , two details :1- i think your choice to pick the lyrical version with the"serial killer" sequence don't fit at all, cause the song speaks about Europe wars and you make a character profile of a modern killer. it sounds very odd. but when he retries to write his novel, the other story fits a lot more. Maybe trying instrumental or having a more fitting anime for the first half would have been more appropriate.
2-Some cuts felt rough in manner of color difference. i would have prefered more fluid or innovative ways to change from the writer to the stories he writes. the concept made it possible, so it felt bit rushed in that matter.
to sum up, i found it like the ending: unfinished. but i had a good impression of what you wanted to try on this amv who is quite fine for the time you edited on it. i'll be glad to see your next one if you find the time to put all you want.
poke me on skype if you want more clarifications
