In my opinion I would,
Make fiberglass pieces attached to the fenders and doors that start at the wider width and gradually curve back behind the car giving it that tear drop shape below the windows if you were to look at it from above.
I like this, nice work.
Have you considered chopping the top and making a heavy tear drop shape in the back? maybe extending the front about 3-5 ft and giving it an elipse shape like the dolphin?
I'd hate to be a first responder on the scene if you get hit by a semi.
