I like orange one(because it's my favourite color),plastic glossy is -real- considering you have done with Kerky(free)
also great look plastic in MOI render and bee-box logo too (it's jour job)
don't be sad if it toke a lot of time for render:you got many spotlights in a closed scene and many blends (that's Mike's style)
if you want to mantain all them rounded and smooth when export,you have to set the mesh with an higher numbers of polys
so...300Mb model + lot of lights = long time render..it's normal !
