This was influenced partly by Richard Adams Plague Dogs as well as the Inle character from Watership Down.
The products depicted in the painting are made by companies that continue to test on laboratory animals.
The crows are in the shape of Inle and I though Black Angels was fitting in that though the act and natural behavior of carrion birds and other scavenger animals is disturbing (to us) it is part of the natural cycle of life. I see the crows as an active agent of liberation, freeing the lab animals bodies from a life of torment and by consuming and breaking down the body the animal is absorbed into the energy of the life cycle.
