Keith: you did a great job here. The score would have been totally different by using a black background. The viewers missed the effect. Can you believe that I had to look and look to discover that the transition was to sugar or salt! Regardless. Then I looked in wonder! You have a good tool here which may come in handy at some future point.
the lighting here is a bit harsh and has blown out some of the glass. Plus i'm not really seeing double take here? Good composition and timing, i just wish i could see more of the wine and the glass
