A brain in a hand-drawn style combined with a paint drip combine to make a question mark - symbolizing smart kids (forever questioning their world). Solid rounded type in fun colors complete the picture.
#7 is really superb. Was wondering if you can do one with the 'brain' tilted so that the green puzzle piece is pointed down towards the purple word 'creative' ... seems to us to be a little more natural of a brain look as we are viewing that piece as looking a bit more like the brain stem. Thanks! You do amazing work. Is it possible that I could see the 'withdrawn' one you had before again? That was early on in the contest and now afer viewing your rank/ratings and how everyone I ask loves your logo I would like to peek at that one once more to see if I didn't judge it too hastily. Thanks!
An alternative for the type color - orange, being a color that represents creativity, for the "creative" and the purple for "brains. It reads well - see what you think.
Also, the tag line in a color gives it a bit more prominence. It does make the overall design even more colorful - you may or may not want that.
