Hi, thanks for your invitation. Please find my first entries attached. The concept uses the children's block style font to get the child aspect into it. The stars are taken from your review system and are drawn in a child-like style to again capture the kindergarten aspect.
I like both the idea with the block style font and the stars from the review system, but would like to see them integrated in some other ways. I don't like the open space between the letters and the stars.
Couple of alternatives. These use a different children's style font and include the starts within the lettering. Also added a smile to the g to add a friendly appeal. Other version has the stars within the smile shape.
