Okay..
I've watched this series intermittantly.. I simply have to say that the ending was one of the laziest I've seen from someone with obvious talent.
Creation is a bitch.
Animation is painstakingly murderous on your social life.
But when you make a commitment to a story, you should either complete it or just not bother. The animation was smooth and the music appropriate. Your storytelling ability is poor. Anything, even a five second flash into the future, with the title character forever grieving/dead/WHATEVER... Would have been a better completion than the supposedly SHOCK ending that you gave.
It seems VERY apparent to me that you simply wanted to end the project. Understandable, but you put it up here for public viewing. I think it was DAMN lazy of you and way below your abilities.
