Are these characters too Mary Sueish?

Well it's not the looks that make a Mary Sue, it's their personality. If they have boys leaping at their feet and if they get whatever they want even if they don't deserve it, if they are good at cooking, singing, etc. etc. courageous, bold, daring, perfect then that is a Mary Sue. You may want to tone down their beauty a little bit since no one is perfect but a Mary Sue is not made up by simply looks alone.
