The decals are placed very accurately, the one thing I'd do to improve the car is to change the paint finish, in the pictures, the car has more of a matte finish, as supposed to the real one, with a more shiny paint finish.
All in all, it's worth you taking your time, the car looks amazing. It's almost as the car is made for this livery, with the chassis vaguely similiar to the real str12 chassis.
Thanks for the feedback!
