I chose 'Ahasuerus at the end of the world' by Adolf Hirémy-Hirschl simply because it's one of my favourite paintings.
The painting has an interesting rythm through the placement of the figures ice and crows. There are various digonals at work in this painting that create a visual flow and balance. I believe the primary focus is on the figures in the background and the eye is lead down to rest on the female (secondary focus) in the forground. The rock at her head leads the eye back up to the start of the main diagonal ice mass where the eye is lead around the canvas again.
I believe the crow in the bottom right corner is key to the balance of the picture and the wing placement helps reinforce the flow to the forground figure. The crow above her derriere and the diagonal of the ice under the angel helps hold the eye in this postion.
Visual weight is acheived in the diagonal placement. The light of her head with the light of the ice in the bottom corner, the dark crow balances the dark mass in the top left. The dark figures with the dark areas in the female hair and above her head.
There is variety,contrast,balance found between the sharp and harsh edges of the ice with the softness of the fabrics in the clothing, clouds, angel glow and the skin of the figure.
I have to work on my edge control. I seem to have missed a lot of the sharp edges...
