Each time I have brought finished models to NNL east they have been photographed and published. If you know me, my models are all highly modified and out of the ordinary and fairly detailed. Even though there were many models built better and more accurately than mine, I still got published.
The moral of my short story, if you want to be in a magazine, build something that stands out. As has been already stated, a common model, even if built to perfection, might not catch the photographers eye.
