Turning a child's artwork into a photo

I've been busy lately and have lots of entries in my head, just have to find time to do them all, hopefully in a few days time.

Meanwhile, I found this through one of the fifty billion blogs I read...

It's a Korean artist/photographer's attempt to recreate children's drawings. I am totally amazed. How much effort it would require to style a photoshoot like that? But I love the fun atmosphere, the quirkiness, the whimsicalness (is that a word?), the creativity, the colours, the cuteness, everything!
