I'm a little conflicted about the MC's appearance... in particular the huge, bimbo lips. Part me of me thinks an invisible protag would have been better here, that way the reader can imagine the Queen however they want and it would save you time and money from having to make different models just for customization's sake. Unless, of course, that's something you really want to do.
That aside, I love Masahige's design and the premise of the story. I'm curious to see where it leads! ^^
