If this were sharper (allowing the features to be more readily identifiable) or more abstract this would work much better. As it is, it has enough recognizable features to make me try for a literal interpretation, and nothing I can identify is particularly interesting.
i think the condensation and light through the glass looks beautiful. compared to the glass, the coaster looks a bit washed out and lacks the interest that the glass holds. i would be interested in seeing how this image would look in b&w, with all that groovy lighting in the glass. i would also be interested in seeing how this image would look with richer colors in the coaster.
