The front wheel wells remind me of the Saab 92 prototype [citation needed]. It had fully enclosed front wheels in a wide body, where yours are close-fitted like current BMW practice.
But underneath there is a gaping hole. Allowing for steer angles, a plate with a wavy outer edge would enclose maybe 50%.
Insofar as front skirts are concerned, I did a design in 2014 (
that is frankly embarassing, and should be redone), that uses a Watts four-bar linkage to suspend the skirt. The significant feature is the top two bars are connected to prevent racking.
