Colouring book paintings

I was just browsing deviantART today when I came across a trend of taking colouring book pages, and colouring them in the style of a classical painting.

My favourite is this one of Aurora from Sleeping Beauty by yumedust

Here are some others I love:

1. Mar-ka, 2. meMilly, 3. Sam Nielson
4. Ryan Wood, 5. loish, 6. ddrbean
7. lil-blue02, 8. britt-ish, 9. elestrial

I think it's such a clever idea! Apparently it was all started by Ryan Wood. They're all so beautifully done, they make me wish I could paint (digitally or otherwise). Alas, this was my last attempt at drawing Disney princesses - done when I was 15. Oh god, I feel old.
