#1- I like this one the best as it encompases family who seem joyful and happy. I like the font. I wonder if the circle is supposed to represent the earth? If so I like it.
#4 - I like the happy aspect of this adn the colours (although perhaps add orange and a darker red & green?)
#5 - aagain I like the joyful aspect of the person and the flowing & colourful font. Maybe add some red?
#6 - it's a bit too cartoonish but it has something in it.
