It's a nice picture, I like it, but it's not very creative. I like how you can see into the glass though, and how you can see the milk being poured into the cup. It's slightly more interesting seeing milk being poured into a glass than if the milk has already been poured and it's just a glass of milk.
imho... maybe a different perspective or a different coloured glass would have made this shot more interesting... don't get me wrong.. I do like the shot!
This is kind of ho hum. Not alot of pizazz. It might be more effective on a black background or a solid white one, shot from the side and not up and over. It needs to be a little better focused as well.
