This is a purely fictional car I am working on, it is a British/Italian style 70s grand tourer. It draws inspiration from the Iso Grifo and Jensen Interceptor.
I started with the idea of making a classic car with a big glass hatch… and here are the fruits of my labor.

A lot was done:
The roof was curved a little
Front slightly shortened
Rear glass was shortened
Other tiddly bits
Looks cool man, are you rendering in orthographic view or something? Field of view seems a bit off…
Model looks very nice, but maybe instead using a uniform textured plane, try to use a shadow catcher and composite final render over those backplates. Shading and lighting looks fine, and camera position give good impression of this monster 
cool car solid work, keep going!
