Nice!
Looks-wise, the only big turn-offs for me are the headlights and taillights. The headlights as they are just don't work. Maybe something more angular and S2000-esque? Definitely don't put "crystal" headlights on this car, the headlights as they are totally ruin the lines of the front so you want some headlights that will fill in the contours of the car.
The domey taillights look silly, I think a TVR-like cluster of surface-mounted taillights would look better.
Everything else looks good, the windshield actually isn't bad. Definitely brace the roll bar against the rear of the car.
