The biggest problem I see is right there in the thumbnail, in Cyan. Vortexes don't work that way.
At 12:24 it turns into an ode to the Nürburgring.
The overall shape is a container for the content, not a fairing. Else it would look like [the top half of] a DC-3. Some details like the sculpting of the rear wing end-plates suggest aerodynamics is more important than fabrication. A flat plate likely would have more drag. The air curtains and vortex generators prolly represent some gain.
OTOH to my eye, mixing slots and meshes on the openings is like mixing stripes and plaid ....or belt and suspenders.
