At first it reminded me of the movie
Haze. But it was only in the premises and the first part of it. I think you should not alter it much. I liked that claustrophobic feel. BTW, it's a quite unique depiction of an object's life.
Sorry if it sounds a stupid question, but I would like to know if there's a particular reason behind your choice for the assignment or the fact of picking a teardrop just as your subject wasn't something you had to think about for a long time. According to your second post, it was a quick piece of work, so maybe you just decided to choose the first thing that seemed original and appealing enough.
