Hi Defour,
Could you remove the wording from either #21,22,23 so i can see what it looks like without the wording, and just the symbol, so i can see what it looks like without wording.
I like #2 because how the symbol works with the wording, but I like 21,22,23 just for the symbol, the wording in those just don't work for me.
Could you also try reversing the smile, meaning the grin on the corner is on the right instead of the left.
