New to Contemplative Photography

Hi, I have been taken photos for more than 10 years, and just came across the idea of contemplative photography... but I am loving it! I have just ordered the book, then so far what I have read is what is in the website and the fabulous images from Andy, Michael and all the contributors... but I feel that most of my work has been along the lines of being contemplative rather than thinking about the subject matter. I always had thought that my mission as a photographer was to try to transmit the beauty that I see so evident, but that many people just walk along. Anyway, my question is if it is ok to submit old photos that haven't been taken for the assignments but that I feel the moment I took them was rather contemplative? Thank you very much for your amazing work! Cheers Martha Carrillo TwoPointEight
