it's a neat statue, but i don't understand how it meets the challenge. the flag pole is a bit distracting. maybe from another angle without the flagpole or where the statue does not obstruct parts of the pole/flag. i like the sky and the colours of the clouds.
I am glad you preserved detail of the firefighter's coat despite the relatively bright sky. An outline figure might have been easier and more iconic, but would not communicate the sadness nearly as well.
Nice comp and subject, though I find the colors a little flat. I think punching up the colors with some curves adjustments may have given it some better pop.
