This is great! One suggestion I would offer to improve this would be to inject the BR tag in-between the opening and closing tags for powers/tactics, background, personality, appearance and other fields that allow free-form text to preserve the line spacing and breaks a player puts into those fields. I did this for my copy to get just what I wanted for a character sheet - attached it here to save others the trouble.
