It reminds me (close but not quite) of Duela Dent: The Joker's Daughter who, as it turned out, was actually the daughter of The Jester (hero version of Joker) and Three Face (female hero version of Two Face) from the parallel Earth 3 universe.
thanks a lot! the artist can use whatever tool he finds to make the creative process quicker. i dont see using photos like cheating. i think is smart. . . but of course. the hability of drawings get lost with time of using photos.
