Like the smiley face under the g's, especially #1 though not crazy about the upside down g's, we do like another design submitted where the g's are facing each other (right g is flipped to face the left)
Like the typeface in use, crisp and clean. Not sure on color palette. Somehow we'd like to portray fun children's products and also give customers a sense of confidence about us as a company.
Following up on our comments, we'd like to see more variations on your designs. Among the variations, do some that are as simple as possible -- no gradation, just one color, etc.
