#47 Everthing on the right side is perfect (the font, the colors, the vertical line, the positioning of the slogan).
Maybe somone can build an icon looking like the cloverleaf from #29 , but with only 3 leafs (left, right, bottow left) and maybe its possobible to move the qrmore in the empty space where the 4th leaf should be.
I think its done... It conveys what you want it to with a simple, clean, modern appeal... heart + code = qrmore... All the extra 4 hearts flipped around with little squares coming off, etc - just adds confusion/complexity that isn't needed... clean & clear design with a strong message sells...
here are some links to some of the best branding work going on today... you'll find that this would sit along side the majority of the stuff nicely... In the end I know its your logo, and your vision, but this is me simply trying to help as its what I do for a living - brand companies... hopefully your open to advice...
