Water Colour in Animation

On a aesthetic aspect in my own opinion water colour can be a great way of presenting a certain atmosphere of the background. What I used in my current animation is a mixture with the background painted by water colour and the whale being cut out digitally but created by water colour as well. It has fulfilled my expectation with the effect that I wanted to create at the first place. Therefore I think water colour has a wildly applied use in animation but not being restricted by the style. 

Below is a set of the screenshot of a masterpiece Chinese animation called MUDI, it is all done by water colour each frames on special water colour papers. The other one is also an example of use of water colour in animation. What is different to my animation is that the characters are animated in water colour as well, while I animated mine digitally in Photoshop.
