This
one is pretty obvious -- starting with an empty bird cage,
what do you put in it? The parrot is a modified Photo
Object. I masked out bars from the back of the cage that
were 'behind' the bird to make the parrot look 'inside'
and then added a few cross bars on the roof of the projecting
part of the front to reinforce the depth of the cage.
I used a rough brush on a mask of the paper to give the
torn edge.
