Vincent Van Gogh🎨 achieved his most beautiful effect of branches with foliage against the sky in the Pine Trees against an Evening Sky.
In reality, the scale of the overall scene is such that it cannot be taken in at one glance, and to paint the trees and the sky like that Van Gogh would have had to gaze up above his head.
The artist was of the opinion that the picture he provided here of the asylum was fairly pleasant and his aim had indeed been to 'reconstruct it as it might have been by simplifying and accentuating the proud and immutable character of the pines and the clumps of cedar against the blue'.
