Maybe less drops of water on the cup... and make some of them leave streaks, which you can probably do with a layered shader with the main cup texture and the drops with a bump+transparency+spec+color for just the streaks. Also you might want to make them all look so regular, like scale some up and others down, you know? I like the bucket of ice, its pretty cool, but theres something about that ice that just doesn't look right. Its probably the fact that the ice is a bit too... shall I say bright?
