I've just updated HeroMachine 3 with a new set, "Mouth-Female-Standard" that properly positions and sizes all of the old items to fit on the female figure's head. This should complete the set of gendered features and make it easier to create your heroines or villainesses. As always, you may need to clear your browser's cache (but not Flash cookies!) to see the new option appear.
While moving these around I kept thinking "Man, that dblade does some nice work." So thanks again, sir, for your fine artistic skills and generous spirit!
