I think a little bit of antialias would do wonders to this. Right now it looks a bit rough. And the melting animation looks a bit silly if you pay attention to it.
Awesomeness ^
should make the drops come in at different times to look more natural
it is neat, but -unfortunately the drops / melting animation does not have any visual physics... ^^;
and as the others said, anti-aliasing might actually make it look more interesting.... i think. hehe...
