good idea
but slow down you dont need to tell the whole story in one flash. just take a part of it it doesn't even need to be the start, but pick one bit and animate that. take your time let the stroy come out. i liked the idea of the dude escaping the city and finding some power to come back and defeat the ruler of the city how about u follow that through.
in the in all i can say is slow down. u have the rest of your life to tell this story so spread it out a bit.
go get a cheep mic and record the narrative i hate text overs
