This skin suits the car perfectly. If Ferrari raced this car, it would look like this. However, you forgot one detail, the ambient occlusion layer. It may not seem like a big deal, but AO helps the cars look more realistic. It can be easily added with Photoshop, but I suggest you to update this with the AO layer placed above the skin in the DDS file in multiply mode. It can be found on each car's template file.
