Oh, I like this one too! Now that I think about it I think I like this one more that your first shot on this subject. Love the light trail that seems to be escaping from the glass!
I like the composition and the splash of light in the background really makes the shot. Overall the image seems a little dark. I like the first one better. IMHO
Nice shot! I love the lighting in this, especially the way the light on the background is kind of leading away from the mouth of the glass. One thing I noticed though, the shot seems a bit tilted to the right (horizon line). If the tripod was level, that might be from not shooting plumb (straight on) to the table. Maybe rotate ccw about 4% and then recrop. Let's see some more, this is excellent!
Edit: I see you fixed the tilt in the other one, but I still like the lighting in this one better.
Very cool! I like this image. Looks like the same glass that did the milk (glass tipped) and the Oreo cookie rolling along - was that you too? ;^) The composition and lighting on this shot are right on. Bet this one is headed to the print shop... Take care.
