The appearance of the fallen bird is striking to your heart, you cannot believe that something so beautiful can be so depressing. the contrast of the colors and the black and white is subtly denting my composure. I interpret this artpiece as a mental state, you feel like you were once a bird, soaring high above with no problems, but on the ground you are utterly helpless. This also may be a metaphor for childhood, like the saying 'leaving the nest', like a bird, you leave your mother's arms and "fly" out on your own. Only some make it.
The theme I see is the bird. The bird is the brightest thing, and yet the most deafening.
