Very well done.
Been waiting for this for eight years, and finally saw it today. Strongly animated, good (non vocal) performances from the "cast", and it kept me engaged for the entire twenty-five minutes, which is by no means easy for something with no dialogue.
Not a huge fan of the ending. It's been a very bleak series, and with the death of a very important character at the beginning of the show, I assumed it'd end on a bleak note, but about twenty minutes in, you very quickly get the feeling that somehow the Biker leader is going to get killed, and that the protagonist is going to escape. It seemed sort of predictable and sort of sucked all the oomph out of the climax. I just had the feeling that I've /seen/ this story before, and I knew how it was going to end.
At the end of the day, they're your characters, and you know them better than I, but I was looking for an ending that would thrill me, and it ended up just being one that made me go "yeah, that makes sense."
That being said, it was very well done otherwise. Again, good work. Solid conclusion to a story a decade in the making.
