That's a great shot. I love how you kept the silhouette of the buildings to a pretty dark shade, just looks really nice. I assume you didn't do any snap-zoom to give the clouds a slight wispy motion blur-type thing, which means that the sky did look quite cool. It was like this earlier today, here, as well I love the orange lens flare, it's great when the sun gets that tone.
Well, good composition, I like how you have a somewhat consistent wrap of foreground elements and it looks like you're facing the dead eye of the vanishing point of the clouds, meaning, you are facing the center of its epicenter of the 'explosion'. Well done overall, I really like this
