I like it. This is an simple and clean exercise. It's not discussion regarding the "Do's" or "Dont's" in Corona render engine. Of course, never you won't be able to see in real life that kind of aberations but I think that aberation it's just a simple reflection...
I bet that you all guys will make the same thing with this 3d scene! Wanna bet Makovsky that you won't be able to make a better image?
Nice and clean ;) I was always fascinated by this "lightbulb 3d experiment". A real life example of glass,metal and plastic combined with the an illuminescent material.
