Its perfect in black and white. Its putting the right message across.

The whole point i work in greyscale is i don't want too many colors destracting people from what i want them to look at. Ie; the sky.

Clouds look fantastic, very sharp and clean

IMHO i would have made it darker, i just increase sharpness and brought the brightness down in photoshop and the clouds are well emphasised

I like greyscale
