Wow. I’ve always been attracted to sand storms because they offer such an interesting atmospheric opportunity. I personally run out any time there is even the slightest trace of fog. Anything that gives the air texture is exciting for photographers.
However I don’t feel your subject matter or composition highlights the beauty of the storm. It’s not that you need to be out in the desert, or even focusing on the sand, but I do feel a different angle could have helped amplify your story.
I like the idea of using cars or some other urban setting, however, I feel you either needed to focus in on a particular area or pull out to show more of the city. The way you have your image framed now doesn’t tell a strong enough story. It communicates the fact that there is a sandstorm, and that you’re in an urban setting, but I think you could push this idea a little further with better composition.
Like I said, I think you should either include more of the environment in the photograph and contrast the sand with the urban setting. Alternatively find an area where the sand has built up and get in close and compose your image in an artistic and engaging way.
It’s not a bad photograph, it just has a lot more potential.
