Warner stating that the character is pretty much finished, means he'll (sadly) settle for the current status of his character and move on into a next project.
I just recalled a story from another time and place. It's not the same story, but there's still enough resemblance to make it interesting. In this story, a man had finished a tribute, a complete remake (all that remained of the original was its general style, ideas, feeling).
The original creator with his original creation had somehow inspired the man to do this work, but now this man was uncertain of how to proceed: the original creator had long passed into the realms of myth, and the man did not know whether it would be right to share his remake with the public. How would the reactions be, how would his work be recieved, what would they think about him for having done it?
First the man asked his friends, but they offered different opinions---he was still undecided. Therefore he simply opened a public topic in a big English-speaking forum and asked everybody else. After the topic had run its course, the man had decided on a compromise: since so little remained of the original, he changed his already finished remake, removed some of the original's trademarks and made his tribute into a different, almost entirely new creation.
In the end. the man shared his private tribute with his friends, and the changed version with the public.
The place was the MUGENDev, the man's name was Elisha and today, nobody remembers Silent Storm. Today, when we think of Silent Storm, we don't tend to think of the guy Silent Storm or his creation, Silent Storm's Silent Storm. When we hear Silent Storm today, we think of Eli's Silent Storm. And only the dinosaurs and those who read and watch attentively among us are even aware that behind this, there once was another Silent Storm.
Obviously there are differences. Eli remade everything, not just sprites. Silent Storm the person had passed into myth, but it was mostly a negative myth. And Eli's two versions were inarguably
better than anything Silent Storm himself ever produced, so that you could say the best thing Silent Storm the person ever did was to inspire Eli to make two characters.
