Butterfly or Butterflop?

I've been tinkering around with the idea of making some butterfly brooches for quite a while now. I had a little bit of spare time Saturday afternoon (after a big sleep in), and this is what I came up with.

I'm not quite sure if the size is appropriate. I need to make them large enough to easily disguise the brooch finding at the back, but I need some more opinions.

Do you think the size is too large, and would you wear it?
