Finished the details and highlights of the wine and glass. I added the light refraction highlights to the glass and made sure that I had the proper shapes, as lights tends to make some crazy designs in glass. There are a lot of different hues and values that needed to be right to make it look like light was actually shining through the glass. Since the glass is round I had to make sure the highlights were not simply straight up and down until I got to the middle of the glass, and then since that part of the glass looks straight the highlights had to be straight.
(thanks to DUO for the "flare" brush! It makes a perfect sparkle for glass!)
