#25 really came up with the "Wow"-effect, but I'm a little concerned to handle this design on the website. A complete dark-green background might work, but the chance that it will not work is even higher. Just think about grafics/pictures on a dark background..
I liked #3 right away and still like it. There are only two directions to alternate the design (and may be improve it): the shape/size of the crown and the color. My be you sleep one/two nights over it and get a fresh view?! But once again - great design!!
