For #18, I'd like to see the "Yes" and the "E" to be stronger relative to the arc accents that surround them. Feel free to use your discretion with variations on the colors, highlighting, etc.
For #16... which could easily be my favorite. I like that it has a single accent 'arc' that is shaped like a crescent moon. That is actually very relevant to our community since the name is "Half Moon Bay". For #16, I would like the "Yes" to stand out more from the accent arc, and the "E" made from stars isn't working for me. Can you show a variation with a different type of "E", not made from stars.
