My 2nd choice of the challenge. 8 I do wish you'd cropped the left and top a bit... to make the scene even more dramatic with the smoke... or whatever that awesome stuff is!
Still... I'm bumping to a 9 because it's in my top three. :D
I like this image, although after seeing some of the other entries with a background scene I couldn't help wanting to see either that welding mask head on (which it appears would be troublesome with that wall right there) or to have more of the scene included in the background.
Well composed. Your choice of B&W gets away from the sometimes trite blue arc and encourages the eye to circle the image instead of focusing on the it. Good luck.
this is great! The pattern on the head band and the mask give extra power to this shot. I only wish you had cropped it on the left side before the white "thing" in the background
