Nothing is explicitly wrong, but the spacing on lists and headers can look kind of silly. For instance, consider in Google Docs - the headers stack nicely, look clean, and lists have perfect indentation / spacing Those changes pretty much cover all this does, and it doesn't do a great job IMO. I'd let them get away with "look slightly better than defaults nearly everywhere"
