We like the font in #37! But the icon doesn't seem to stand out like some of the other icon ideas we've seen. Ideally the icon will stand out and look unique to our brand.
Also, I might suggest changing the secondary color from orange to green. I think that would go well in this usage.
Thanks for the two new designs! I will pass these along. We extended the contest by 2 days, so now the new ending date is Tuesday. That should give us a little more "breathing room".
