Although the front is a bit different now than what it was in the sketch, the fangs became the defining feature of the whole car. When I was searching for more references the face-like front brought the Green Goblin character into my mind. That, in turn, helped in designing the top surfaces and the sides.
Also, I'm a big fan of Jakusa's work and I gotta say, his Triango concept played a part in inspiring me how to arrange the headlights. fav.me/d36n8xa
