Hi Cynthia,
Thanks for all these entries.
Bottom line is that we're not interested in the style of #344 (and similar), and we don't love the LD of the other ones. The recent entries are very similar to our current first choice by Charles Sells, but the broken circle is a bit busy for our taste.
Since we're near the end of the contest, and happy with our first choice, I don't want you to do any extra work if it's not going to pay off.
Thank you again!
- Andrew
