Lightsong was one of the more "real" feeling characters to me. I know that may sound a bit odd, but he didn't take himself too seriously, was willing to point out his own flaws in character, as well as others, and his humor was one of the most enjoyable parts about his sections. Some slight tweaking, maybe, but I don't think that there is any major character changes needed with him. His brutal honesty, with everyone involved in his sphere, is refreshing when compared to the games that are played in the palace and other places. I can't think of a specific thing that I would tweak or refine, but if you feel the need to do something to him, that is all that I would suggest. Maybe an overall refinement of his conversation, and interactions, but I am not entirely sure that there is much room for refinement. Even in version 1.0, I enjoyed Lightsong and his sections were the most fun for me. Laugh out loud funny really, so much so that I would have to read a passage to my husband to explain my giggling and laughing.
