It was a joke, obviously. In the TOR cinematic trailer we have a red-haired female bounty hunter that resembles this drawing in armor that resembles Boba Fett. Hence the irony of a parody drawing posted one year ago actually becoming a valid artwork.
The fun thing about Mandalorian females is that they are very open-minded sexually and they will always say yes when asked to have sex. The bad thing is that once you mate with her you are bound by their customs to become a Mandalorian yourself. Otherwise she will hunt you down and kill you. How cool is that?
