Very Nice
It was a fine piece of work, which was surprising. Although I have to admit, the story has an abstract start and thus requiered me to catch up for a moment, it flowed nicely. Btw, you made wonderful use of the same background texture, even when colorizing.
And, Specusci, Anime is a largely Japanese style of animation which grew to include other countries, but not many. Korea, north or south, has little in common with Japan. It would be like taking a Mexican's opinion to heart on the topic of Canadian politics. I'm sorry, but what you said was fallable and based entirely on opinion.
