Amoeba or Raindrop? - You be the judge

A couple of months ago I found these great wrap sweaters. I love them and I bought them in three different colors. However I needed a brooch to dress them up and keep them closed if needed. Here's the brooch I made.

The rivoli is an incredible shade of blue/green. While I was beading it, I kept thinking it looked like amoeba especially when I added the fringe. But now when I look at it, it reminds me of a rain drop.

What do you think?
