To choose to serve. An honorable decision, however this image does not alone invoke that decision. It tells me a story of honor, recognition, memory. It is a well shot and processed image, but a weak link to 'decision' that to me would have been better (militarily) posed by a young man or woman approaching a recruiting office. I can only offer a 4 compared to other images that seem to communicate the decision in a more obvious manner.
Nice photo - good strong colours and an interesting subject. Unfortunately I feel that the title is required to support the challenge criteria, which may result in lower votes by some.
