The black and white choice and the light blue color dominant contribute to create a mystical atmosphere in this marvelous artpiece. The elements are well placed, in my own opinion, in the square canvas,and the composition is nice and well balanced.
Three points of disappontment:
I'd rather preferred a larger size of the picture for a more careful analysis.
Maybe it's a trouble of my monitor but I see a yellowish halo around the illuminated area in the middle of the top area.
the opacity of the mist above the hedge. Maybe a lower amount would have been appreciable, but I'm not sure: maybe as it is it contributes to give more depths and spectral atmosphere to it!
Well, the strength of this artwork is given, in my opinion by the geometry of the field wich is continued -not interrupted- by the texture of the fur of the giraffe.
