I think Michael's actually quite impressed with it too.
I love the contrast between it looking as if it's going to be a "pretty" thing, but it's really full of the horror of the birth, life, death cycle.
Little birds perched on the twigs, dead body impaled on a thorn, baby with the right size of head - but middle-aged man's ugly face (nice contrast to the usual images of the christ-child having a small head - in adult proportions).
The cockerel seems to have a human arm, and I really can't work out what sort of creature the part-snake, part preying mantis, part pea-pod/wormy thing with chicken feet is at all!
It IS beautiful, not pretty at all.
Very hard to photograph - the images are all curved!
