Hidden Smile Face on paintings

I added the ink swirls and my usual hidden smile face :-) signed the artwork and it was ready to swirl towards whom ever ends up with it. I wonder if they will notice the smile one day. Below is a zoomed in look at one.

I have added hidden smiles on over 1,500 hand painted whimsical animal & flower watercolours that have gone to customers all over the world (since 2011) when I started out as Artist Sophie Appleton.
