I like how you scaled everything to the smiley faces size to let them set the cheerful tone. (It worked, I'm smiling.) That raggy edged banner is the BEST!!
What a super fun background! Awesome smiling white space! Great photos and word art. Love your clusters! The flair that apparently just got his braces off is a hoot!
