Just created this artwork titled defoliation #2. Here goes my attempt to explain it, without getting too carried away.
The artwork represents the diminishing food supply for the birds in the urban areas. The black and white with the leafless trees help to represent the lack of food. The birds flying around represent the effort to find food.
The pattern merge comes from looking at too many MC Escher images and loving his metamorphosis type images.
The trees and the cloud lines are from a photo I shot in a local park, on a cold winters day. The shags flying around were shot at Napenape beach.
