Both are beautiful, but the b/w version gives you a sense that you could almost put a ladder on the clouds and climb over them to see the stars in the attic.
I think I like the b/w better due to how the clouds just pop out more.
Beautiful and well executed photo! I lean towards the color version on this one but, as others have already said, the b&w brings out detail and texture that is not as obvious in the color version.
