Portland Rose Festival is a title not a headline. A headline should lead a casual reader into a story about the event with some kind of information or tantalizing tidbit. Assuming this is a story about the Rose Festival, this is not the kind of photo one would see supporting it. This looks like a submission from someone unwilling to go outside the safe boundaries of their favorite subject matter to find a newsworthy subject to photograph. A human element would have added some journalistic integrity to your effort. Without that, I have to conclude you couldn't be bothered to make the attempt at photojournalism.
Photographically, it is a nice flower shot but there is nothing about the composition that makes it stand out from the hundreds that can be seen on DPC. It's kind of a 'if you've seen one, you've seen them all' subject that requires that extra effort to make me sit up and notice. For starters, I would suggest a square crop placing the rose dead center.
