It looks like the normals on the geometry are facing the wrong way to be honest. I think the glass is modeled to be pretty thin, perhaps too thin to be realistic.
Thank you for your critique, and you're right, the walls of the inner glass were too thin. But I pulled them in a little bit, and created a glass material using a Blinn shader. To me, it looks so much better now! But my new issue now is maintaining the reflections, but getting rid of the reflections of the stem and the foot off the bottom of the bowl of the glass.
What do you think?
