Sunrises and sunsets are a tough sell in most challenges. They're shot often and as a result, there has to be something truly spectacular about them to make them stand out. Moreover, in the DPC Universe, there has to be some connection to the challenge. In this case, I'm afraid, you've got neither. It's not a spectacular shot of a sunrise, nor is there any reasonable connection to the challenge other than your appending the word to the title.
What's triumphant about it? Its a nice picture and all, but I dont know, there always seem to be sunrise pictures in every challenge no matter what the theme. It doesnt fit to me...
