Audi R10

This is my first attempt at modeling a car. I made this last year for a school assignment. We had 2 weeks to model a car, but due to some confusion with our class schedules, me and a couple other students found out when it was due on the day we had to hand it in. I worked for 16 hours straight to try and finish, but my reference pictures were a little confusing, so I'm missing the vents at the side, side mirrors, a steering wheel, wheels (not just some wheels I added 5 minutes before I had to hand it in), and probably some other stuff too.
