You are right, many need fixing, I will get to it next week. They were generated some time ago - since then there have been a lot of progress in AI and new tools to deal with such issues, it's time to refresh this pack and add some more interesting portraits too. Hope it will be useful for you as it is for now, if not let me know, I'll refund you.
