Thank You for your entries and your work. Of the 4 entries here, I like #16 the best, then #17, and entry #14 the lest. Mostly because of the brain graphic. I don't like it flesh colored. Also, I have asked for some examples of different font. Here are the things I like about all designs.
1) Brain graphic - which you did tanks.
2) Set off or highlight the "bill" letters as part of "Cerebillum" which was done in the entry I currently have ranked as 1.
3) I like the idea of the brain having something surrounding it signifying an idea or a solution. You did that in entry #17 and #16.
4) Use of color
5) Provide some different font options and even perhaps a more complex graphic.
Thanks Again for your entries. Please continue to submit.
