I'm with Joe...
This wasn't all that good. I realize in anime there rarely appears to be a constant plot in the begining, but this was nothing more than a long empty road and a bunch of gang bangers then a blood bath. I'm afraid your mistaken if you think that makes a decent quality episode.
Your animateing is pretty good for fbf though. Lil' rough around the edges, but good none the less. The placement of characters against the background was just terrible though. at times, the placement had it so they were talking to each other while facing in opisite directions if you went by the background as a marker.
And pretty much this entire movie was a scene from "Kill Bill", from the lip bite on. Then it was nothing more than cut, bash, slash.
Plus, from what you said about the character in the notes, sable is NOTHING like that character. the sable from the movie was a vilont, blood-thirsty sadist type by the way she never out right killed a guy and even smashed up the first guys face after she killed him. That doesn't sound ANYTHING like "an enthusiastic but unlucky girl, who always means well, but just can’t seem to stay out of trouble" to me.
Your animation was good, but most everything else needs work. And tell your friend that his music was incredibly clishea and either you or him need to work on back ground placement for the characters. There were alot of errors in that department.
