Looks Great. I liked it. We shall go with this.
For the banner(full logo), we can use full person Juggling(https://en.wikipedia.org/wiki/Juggling) multiple category website drops like in http://www.freelancer.com/contest/Design-a-Logo-for-Drupal-Project-One--23334-byentry-1367353.html
for the website logo like in http://openatrium.com/, we can use half person without juggling and title & caption to right/left.
what shall we do for favicon as it should be small & recognizable?
how about using number 1 with drupal eyes & blue color as favicon?
