The hollowed mushroom shape of the explosion I find really fun to look at. Great piece!

Very strong composition, with excellent use of light and dark. It's a small detail, but I really love the lighting on teh buildings in the background.

Great concept and it was executed flawlessly, love the contrast, and the glow that hit the building in the background, the cloud's swirls in the sky, the shadow in the ground, Amazing work!! 

Love how stark the contrast is between him and the explosion, wonderful work!!
