I was liking the project till those photoshop picture...eek
THINK Morgan
V shape the hood wider in back narrow in front slope it as much as you can... The car is narrowed so fender flare the wheel wells no need to bullet the nose slope it back and incorporate a nice angle to deflect the wind back almost 30 degrees or as much as the car allows use an angled grill that scoops air up low and cuts it giving it a better aerodynamics

similar to the grill on the Morgan but more of an angle back at the top.
Look at the Morgan Aeros face get that grill and hood make a mini version of this sports car it will be cool as hell from the front I can see it in the work you have already done you have a great shape for it. No reason eco can't look bad ass and cool if the design helps the efficiency.
