The first shot looks like the Lotus should have a Follow Me
sign on the roof. I looked at the second and thought, "One of these cars is similar to the airplane in technology and design philosophy. One is made of stamped steel."
I see you struggling with how to frame two very different things (size, shape, visual center) in one picture. Normal 'family portrait' rules on group composition don't really work, especially because you weren't allowed to 'pose' the airplanes arbitrarily. I don't know how much more you could have done with this sort of material.
