it's looking good but you could problably get that same effect with Maya Software.
I'd say try the MR Dielectric material for the glass part, with IOR 1.52
And try the other MR material that appears in the list for the pen part... ahh I forgot the name
Anyway, keep working on it, and it'll turn out great!
Cheers,
