This looks very odd to me -- the bits on top, what are they? And are those disc-shaped bits of ice? They rather look like coins. I think in this case too close-up a shot. The connection to the topic is fine.
Looks like a lime rickey to me. Don't really know what kind of liquid this is, but the reflections in the glass of you and the other objects is distracting and confusing and reduces the contrast.
