W.I.P of minidisc that I have done, it’s modeled in rhino and rendered with Vray 1.09.03g. The parameters of render are very low, I must correct the texture of the buttons (help!!!).
Of course, suggestions.
My english is not very good. 
I think the material for the plastic needs to be worked on a bit
Bit more shiny, but the butons are nice
Clear plastic also
Nice modelling though, and otherwise a good pic
How did you get the nurbs into max?
Ive had trouble with that in the past
Very nice detail, I don’t think the wood map is doing it an favors .
i agree with chris, it does need to be shinier. all the MD players i’ve seen are either shiny plastic, or have the brushed metal look.
the disc itself looks flat. i can barely see hints of modelling (the tab on the side, holes on the corners). maybe you can exaggerate these features to give them more depth, so the shadows are darker and bring them out more.
