A car paint shader for cycles

It is a drafted car paint shader for cycles(just the first vision and I’m still working on it:)). I mimic the shader from the mi_car_paint_phen shader from MentalRay. It can control multiple diffuse color shift and reflection variation due to observer. You can also output pure diffuse element or reflection element and control the flake bump of the surface by the flake output. But I still have some problems on the flake now, for the result doesn’t look nice enough. I use the musgrave texture for the inbuilding flake texture to get more controlling and details, you can manually use a voronoi texture for the flake bump but the result might not be realistic enough. So if anyone has some advice on improving the result of the shader, please tell me:)
