Hi,
I don't post as much as I sould, but I just couldn't let this contest pass by without trying my chance. I see there are many great designs already posted. Here are mine:
The idea with the eye was to express the unique vision a "photographer" has of the world, even more when is a "Pentaxian photographer". The design is off centered so the red dot is on the left side, right above the Heart
The iris of the eye has nine diaphragm blades like the Limited lenses for better bokeh
I wish it was possible to use gradients and more color but as the rules stated only two colors...
The second idea is about the same but with a more realistic eye.
