The image stitched together is too much information without a focal point. With fires, especially not terribly fiery ones at night, it is best to focus on people, or one dramatic element per shot. Keep trying though, you had good exposure. Be careful, fires can be addictive.
I was worried when I first saw this shot I thought the ladders were melting. Now I understand why they look this way with the stiching of the frames together. Pretty cool shot over-all. I like the lighting.
This image was taken with out a trypod and was three frams I merged into one using photoshop. The size does not do it justice. Her is another image from the same fire
