Thanks for joining this contest. At this point, the bar is raised pretty high. We need something interesting, strong, clean, and iconic (literally - easy to recognize as an icon on Twitter, etc.)
I like the simplicity but this needs something more than just a plain red arrow. Let's see what else you might develop, using the detailed brief and the links to the arrows I like (on the main contest page in the comments area). Thanks - looking forward to your next round!
