I like it a lot! The one thing that I would change is the front end styling. It's attractive and fits in very well with modern supercar designs, but it's perhaps a bit too generic. I prefer something that's perhaps a bit more classic. Here are a few front ends that you might be able to take inspiration from:
The C-GT being my favourite of the three. I guess I would prefer a look with smaller and lower openings in the front. It'll give the car a lower, faster appearance without making it appear too cute or too aggressive. I find that a simple shape with exquisite details is often my favourite recipe for a supercar. Don't worry about adding fussy shapes in the design, just focus on the overall shape, the headlights, and greenhouse. I think once you have those where you want then the rest of the car will just fall into place.
I realise of course that you're way more talented at this than I am, so I'm speaking out of ignorance and personal preference here.
