Oh, what am I reading? I'm only a scene popularizer and some graphic designer as many other. :P But terribly sorry, this time I must pass. If I would choose which icon is the best from above examples, IMHO is the one with a "kite" or "1Pink grey-green". ^^ However, "squares icon" is much more informative, only colours I don't like and font used in "designed by" doesn't fit to the rest.
