I painted the birds and houses on muslin, and tried to make them 3D by stuffing them a bit with batting. I don't know if I like what I did with it, but I tried to show bird's lives and peoples lives together. Birds don't get parking tickets for sitting in trees, and they don't need prescriptions from doctors, or have to write cheques to buy their nests.
I haven't fastened the birds to the substrate yet - I may sew them onto fabric instead. Let me know what you think.
