Hi,

recently we had opportunity to watch artists painting with Krita -- see videos on http://www.krita.org. It helps to both groups -- artists and developers.

Here is collection of 20 speed painting videos, the most impressive painting videos according psd.tutsplus.com I just found today

Paintings are not done in Krita, but might be inspiration for you
