Oh my gosh they are all so cute! I think I like
#33 best after, go figure :) especially for a big sign, very clean.
I still really like the new brains too, #46,47,48. Could you try a white outline or drop shadow around "R!ght Bra!n" to see if it helps it read a little better please?
Also, how can I reach you after the contest for future work?
Thanks!
Nikki
