Well, you have picked one of the hardest things to model. Glass is
notoriously difficult. Just think of all those painters of long ago trying
to get it right. Light is so heavy :-}
I also think that the eye deceives the brain in RL (T) and we see what we
expect to see. So when looking at a rendering the colours can seem
exaggerated or unrealistic. Just keep plugging away and you will become one
of the experts.
That aside, I think your glass is a bit too thick (if you want to make fine
glass) but overall the modelling looks good. The Lights, IMO, are a bit
close to the glassware, going by the shadows.
