And a Novel of your character’s daring deeds, flights of fancy or a description of height or weight.

This seems a bit too barebones if there's going to be any kind of exploration or combat, or activity at all for that matter. If nothing else I'd rather list out my character's story, perks, flaws, etc. by bullet point rather than sunk into a novel. It makes referencing much simpler for myself and other players.

Just knowing what my character looks like and how old they are, like in your current CS, isn't enough to work with. I can find out all that information the first time my character meets yours.

Also, I'd advise caution with open-world freedom. I would recommend having some kind of underlying objective (talk to this person, go to this place, do this sort of task) so that, when we are done wandering around, we have someplace to go to advance the story.
