This could be a reasnably attractive setup if you went away from direct light and tried to paint some drama into it. Like this, the light flattens everything, there's no feeling of depth and therfore substance.
The composition works okay for me. I wish there was a bit more to your background...say some ice or something to add more interest overall. This is the second "Kentucky beverage" shot I've seen. That stuff must taste pretty good. :-)
