I honestly have to say that I think your statement "If you don't care about your pink, think about it! or else yours will turn black!" is pretty tasteless. I also didn't like your statement about "If its PINK, it does not need treatment/surgery. If it has changed its color.. be ready for the battle." as well as this statement, "It is time to think about your pink, if it will change its color, it would be hard to make that pink again...". As a survivor of cancer who presently has three family members with cancer, including one with breast cancer, I find these statements offensive and not well thought out. Just thought I'd let you know.
Personally I would just leave those statements off entirely. Maybe just say something like "Help fight breast cancer". Pink is the color of the ribbon for breast cancer, not a representation of a healthy breast. Other colors represent other conditions and diseases [link] . To say that other colors represent breast cancer is an affront to all these other causes. Your photography is quite nice with good composition and can stand on its own.
Looking through the contest entries I've noticed many people just give the necessary information - that it's an entry for the Think Pink III contest and the category. A few people tell stories about how cancer has affected them and their family and a few people give information about the weekend to end breast cancer. So, you don't really need a catch phrase, let your art speak for itself.
Well, I can see that, but I really think your photography is nice enough and your concepts are clear enough without explanation. Sometimes it's best to let the concepts speak for themselves as the meaning will be more personal.
