Good modeling, but your plastic texture is weird: The objects appear to have
very little contrast. Don't know how this turns out in you scene, but I have
used this plastic texture successfully with radiosity:
pigment {rgb 1}
finish{
ambient 0
diffuse .8
brilliance 1
specular 0.4
roughness .05
}
normal {bumps .1 scale .01} //object beeing app. 3 units wide
