wow thnx!
I did the drops by starting with a outline and a took the air brush (white) and go over most of it which ever way the light is coming from add more white there.
then add a bit of gray on the other side.
and add a little black shadow,
once your done that remove the outline.
also add a little white streak as you can see in my picture make a little bit of white airbrushing around it.
Sorry if it seems confusing but it helps to use a reference for the drops.
hope it helps!
